Browser or OS not supporting “WebEx Meeting Center video conferencing”

[tripu]

Sometimes, when loading the URL to join a WebEx conference, I see this error message:

The text says:

“You can't start or join this WebEx meeting because it's enabled for WebEx Meeting Center video conferencing, which isn't supported by your browser, browser version, or operating system. Contact your administrator for more information.”

It doesn't seem to depend on whether I'm logged in on WebEx already, or not. This happens on Chromium 65 on Ubuntu Linux 17.10 (Artful Aardvark), with a bunch of browser extensions like HTTPS Everywhere, Adblock Plus and Privacy Badger.

[JWillie6]

Same issue here. Just recently started. Did you find a solution yet?

[tripu]

No, @JWillie6.

[tripu]

“It doesn't seem to depend on whether I'm logged in on WebEx already, or not.”

I now suspect this happens more often (or even only) when I am logged in to my MIT/WebEx acccount…

🤷‍♂️

[thapanarendra]

Do we have any solution for this issue?

[JWillie6]

I'm now thinking that a recent system update (Linux Mint 18.0 Sarah) caused this problem.
A colleague just installed a fresh Mint 18.3 Sylvia and this problem does not exist. So that's my next step.

[thapanarendra]

I am using Ubuntu 16.04 LTS.

[mikemhenry]

I'm on opensuse tumbleweed, Chromium, no extensions

[SingularBunny]

Same issue on Ubuntu 16.04.1LTS, Chrome Version 67.0.3396.87 (Official Build) (64-bit)

[tripu]

(Pinging @webex and @adamweeks very quietly here, in case they know who can look into this, or whether we should report this through some specific channel.)

[adamweeks]

@tripu I'll ask around for you and see what I can do.

[fishcu]

Same issue here on latest Chrome / Ubuntu 16.04.

[BenTyger]

I'm having the same issue. Running Linux Mint (Mate) 18.3 /Ubuntu 16.04 with HWE kernel.
With these meetings, we need to be able to let a non-hosts request keyboard/mouse control. The newer webapp version doesn't allow this on Linux at least. The older JNLP client has been working fine for quite some time.

The thing is that with some customers it works fine and others it doesn't. In the same day, the JNLP webex worked fine connecting to one customer. Then later that day, I tried to connect to a different client and I get this message with the JNLP client: "You can't start or join this WebEx meeting because it's enabled for WebEx Meeting Center video conferencing, which isn't supported by your browser, browser version, or operating system. Contact your administrator for more information."

[BenTyger]

Also just for more clarification, both of these connect conferences were with WebEx Personal Rooms.

I am facing the same. How to resolve this ? Sometimes works in chrome and sometimes does not work. In Firefox it never worked for me. I installed Red Hat Linux 7.5 recently and I am facing this. Can you please resolve fast.

This is the error :

Seeing the same issue on Ubuntu 16.04.02 LTS 64bit, please provide an update @webex @adamweeks as this is something we rely on everyday especially when working remotely.

[makandas]

My issue got resolved. I changed my proxy setting to "No Proxy" in Mozilla FF and that resolved the issue. In chrome, I still sometimes face the issue.

Sometimes proxy setting does not work for me. I found another way. Enter "webex.com" in FF -> click host -> enter your mail id and host a meeting. This always works.

If you are joining a meeting. Enter "webex.com" in FF -> click join -> sign in - enter your mail id and click 'attend a meeting' in the left side menu. Enter the "other person id" here. This always works.

The issue looks like some old cache values are creating an issue. Even browser clear cache does not work.

[rmtribpub]

The proxy setting change didn't work for me in Firefox. I didn't change anything in Chrome, but something is different, I see this error now:

Cisco WebEx had a problem processing your request. Contact support or your administrator and provide the following error tracking ID:

[FlyingMG]

What brought me to this error was the WebEx link:
https://www.webex.com/join/username
put into the calender invitation
in some other users invitation the link is looking like the following;
https://www.webex.com/meet/username
this leads me to the WebEx page where I can select to attend to the WebEx Meeting in a browser, which is successful for me.
I am using Firefox ESR 52.9.0 (64-bit) on ubuntu 16.04.x LTS
Hope this can help some of you...

I found another way. Enter "webex.com" in FF -> click host -> enter your mail id and host a meeting. This always works.

@makandas This didn't work for me.

I recently started getting the same problem in both Chromium and FF on Linux. FF is my primary browser with a number of extensions and blockers enabled so assumed potentially something to do with my settings. Chromium I use as a stock browser for testing. What I found particularly odd was WebEx worked on one laptop with same version of Chromium but not the other. I cleared cookies and history (in case redirects to MIT authentication service were somehow involved), no change. Then I reset all Chromium configuration to default and it works again. I have not figured out which setting interfered.

[Aadil672]

@makandas Thanks for your resolution :), "I found another way. Enter "webex.com" in FF -> click host -> enter your mail id and host a meeting. This always works.
If you are joining a meeting. Enter "webex.com" in FF -> click join -> sign in - enter your mail id and click 'attend a meeting' in the left side menu. Enter the "other person id" here. This always works."

But I want to add one point here, While joining they ask for meeting number, so I don't know where we can find that, so there is an alternative > go to www.webex.com > sign in with your organisation id > click on modern view (find right up corner of webex window) > select the person to whom you want to join or person's host id.

[kaanaksit]

Well the resolution highlighted is not really a resolution as it allows only usage of a personal room. There are meetings with ids that one needs to join. I am also on Ubuntu 18.04...

[dancompton]

I've been unable to work around this issue.

[nvibd]

What fixed the issue for me was clearing all *webex* cookies.

[aucampia-emrsn]

Same issue: rhel8 with latest firefox and chrome.

[oliver-wm]

You can add .webex.<your organisation>.com to the clear on exit option in cookies and site data in Chrome. Seems to be a temporary fix for me.

[wwalker]

I did some testing now and verified that the error happens every time I go to a URL like:

https://webex.com/join/username

Based off @makandas 's post above, I fiddled with it a little (the UI has changed since his post)

• login to webex.com
• then click Home
• then, instead of following a link that you have, either :
• click on the user on the right side of the page under "Recent Personal Rooms",
• or use the meetings link list in the middle of the page
• or search at the top of the page.

These all seem to work all the time for me.

[rw-anderson]

I ran into this message today. I am using chrome 81.0.4044.122 on ubuntu. It seemed to start when I tried to open a second webex meeting while one was still open in another tab. After that, I couldn't seem to join any meeting on chrome. (I was able to join meetings using firefox.)

[jat255]

I was unable to join a meeting with Chrome or FF from Arch Linux today as a panelist. I could join as a regular attendee, however.

[oilian]

I am just working with a colleague on his Webex issue as well (Join issues, no option to share his screen when joining as a participant, etc.). One thing I asked him to try out (waiting for his reply) was to change the Firefox user agent (by using [0]) to Firefox 76 and Windows 10. Maybe Cisco is only checking the user agent to define what works and whats not.

RHEL 7 + 8 with Firefox ESR

I do not have a webex account, so unfortunately I can not try this on my own.

[0] https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher

[ajusa]

I am running Google Chrome on Solus, and was able to solve this by using a user agent switcher. I set it to Firefox and everything worked. There are a lot of these extensions, but the one I used was this one. I set it to Firefox (Windows) and was able to join a meeting from a link and stopped seeing the error message from the issue.

[CBtiger]

2020-01 I am also having the problem.
Firefox 84.0.2
Linux Ubuntu 18.04 LTS
OpenH264 Video Codec provided by Cisco Systems, Inc., Version 1.8.1.1 October 26,2019 (seems the newest)

However, I found as @kunguz reported that WebEx works well in Linux in my Firefox when it uses Personal Rooms. Any other Webmeeting does create the error message. You can see what meeting type you are dealing with by the URL link you get:

1. https://SomeCompany.webex.com/meet/someID
2. https://SomeCompany.webex.com/j.php?MTID=someID
   The 1) is the personal room meeting and that works fine. The second is a "normal meeting" (not sure what the official name is) and it does not work, because it does not run in the browser but download an application that then runs the conference.
   Its very easy to check that with Firefox by installing the @ohaessler above. When you switch your browser to mimic any browser on MS Windows, and open the link type 2) you will see a popup that it wants to execute "webex.exe"

So unless Cisco does not finish development of the port to Linux this will not work. Seems like work started End 2020, so I think we can be happy to get anything before end of 2021.

So, next best workaround: did someone get it running in a Windows VM?

[romeokienzler]

PLEASE DELETE ALL YOUR COOKIES - for me it started to work again then (on RHEL 7.9)

[ghost]

Deleting the cookies is not helping in my case

[wwalker]

What also works for me when this happens is to open an incognito/private window and log in there, then it usually (95% of the time) works.

[cdir]

I get the same problem when I try to join as panelist. Incognito/private Mode and deleting all caches and cookies did not help. The good news: I had no problem with the new Webinar until now.
