Unhandled rejection Error: not opened #1853

Jolly-Pirate · 2017-10-26T02:11:17Z

I'm running a local instance of condenser. I keep getting those errors after browsing a few pages then letting the browser idle for a minute or two, then pressing F5. The page hangs for a while, and I end up with a 502 or 504 Bad Gateway. I tried with apache and nginx as reverse proxies, but the problem happens on both. Also, the issue is reproducible on Ubuntu 16.04 and Fedora 26. I setup MySQL, but not tarantool.
P.S. Tested on several RPC's, same problem.
Also, tested straight on condenser at port 8080 without any reverse proxy, the websocket error occurs again. Also happens with steemit/condenser docker image.

Looking a nginx's error log I find errors like this:

2017/10/25 20:01:35 [error] 28116#28116: *9 upstream prematurely closed connection while reading response header from upstream, client: ***.***.***.***, server: myserver.com, request: "GET /created/steemit HTTP/2.0", upstream: "http://127.0.0.1:8080/created/steemit", host: "myserver.com"

The text was updated successfully, but these errors were encountered:

skenan · 2017-10-26T04:09:02Z

Same error when I am running my https://cnsteem.com

I have setuped MySQL and tarantool.

Jolly-Pirate · 2017-10-26T04:11:52Z

I have a feeling it's because of jussi's optimizations, it broke the regular apache/nginx reverse proxy. I could be wrong though.

skenan · 2017-10-26T04:17:39Z

@Jolly-Pirate I didn't use jussi, you use that locally?

Jolly-Pirate · 2017-10-26T05:22:07Z

I don't use jussi, it's a simple condenser+mysql+nginx/apache setup.

KINGdotNET · 2017-10-26T15:25:06Z

@drakos use "wss://steemd.steemit.com" for your RPC node connection.
It should correct those websocket errors.

KINGdotNET · 2017-10-26T15:26:25Z

What I want to see added is to provide list of RPC nodes. If the first one is not working or slow to respond, the 2nd node will take over automatically if possible.

Jolly-Pirate · 2017-10-26T15:33:15Z

The idea is to use a different RPC node, given the unstability and slowness of wss://steemd.steemit.com. Upvoting, posting, etc. are all problematic on that node.

P.S. I tested on that node and other RPC nodes, the issue happens again. So it's not an RPC problem, but condenser.

KINGdotNET · 2017-10-26T15:37:34Z

I agree.

KINGdotNET · 2017-10-26T17:11:44Z

Now I can see this error when I successful logged in and will continue to appear even you logout.
I restart the service, this error will go away and will re-appear when I login again.

The sign up is broken too.
All this error on a second server.

My first server runs without any bug, but this is using the previous version of condenser.
See it here https://yehey.org

skenan · 2017-10-26T21:57:44Z

@KINGdotNET This error only happened in lastest condenser.

Jolly-Pirate · 2017-10-26T22:31:54Z

No, the error has been happening since 3-4 days since I started setting it up, so before and after the new UI.

KINGdotNET · 2017-10-26T22:31:55Z

@skenan correction. It is my mistake, got it working. I actually disabled it, stupid me :)
I have it running now, testing the load balancer for https://yehey,org website.

skenan · 2017-10-26T23:30:38Z

@KINGdotNET you still use the old version, how about trying new one?

KINGdotNET · 2017-10-26T23:38:26Z

@skenan I am working on the 2nd server using the new version of condenser. It seems not stable.
I can browse the site, no issue but every time I connect to sign-up and go back clicking other articles the websockets errors appear. The server will crash eventually.

skenan · 2017-10-27T02:28:36Z

With this error, it's very hard to debug locally.. I feel painful and couldn't contribute to the code.
@sneak @valzav could you guys please take a look at it? Or give us some advice.

bnchdrff · 2017-10-27T02:34:29Z

this is a known issue caused by the steem js lib. to work around this bug:

cd node_modules
rm -r steem
git clone git@github.com:steemit/steem-js steem
cd steem
git checkout ec4439c1319e21ccb4b52a3de3798a37b84b0001
yarn

KINGdotNET · 2017-10-27T02:41:50Z

Some of the errors using the new condenser. This will shows right away, when I clicked the new links on the right column e.g. welcome, faq, pick_account, etc. I hope that help.

@bnchdrff I'm trying to download, permission error.
git clone git@github.com:steemit/steem-js steem

bnchdrff · 2017-10-27T03:08:49Z

you can use https instead of ssh if you don't have your keys set up; change git@github.com:steemit/steem-js to https://github.com/steemit/steem-js

skenan · 2017-10-27T03:19:16Z

@bnchdrff why we couldn't fix this bug at steem-js?

KINGdotNET · 2017-10-27T03:22:09Z

@bnchdrff well done! All errors are fixed.
I will continue to test it and share my results here. This will be a 2nd server to be in Europe for my load balancer using the new version of condenser via https://Yehey.org.

Thank you sir.

skenan · 2017-10-27T03:24:46Z

@bnchdrff Can another way to change the package.json from
"steem": "github:steemit/steem-js#72a36c835a74f446da47e36feea5d5f1f4dde55b",
to
"steem": "github:steemit/steem-js#ec4439c1319e21ccb4b52a3de3798a37b84b0001"?

Jolly-Pirate · 2017-10-27T15:45:51Z

Thanks for the solution @bnchdrff but it's not working for me. When I run yarn from the new steem dir, I get this error during compilation:

valzav · 2017-10-27T15:55:12Z

Probably we need to use global webpack instead of ./node_modules/webpack/bin/webpack.js . Any opinions on this?

skenan · 2017-10-27T16:08:16Z

@Jolly-Pirate Did you try change the steem version in package.json, that works for me.

Jolly-Pirate · 2017-10-27T18:42:45Z

@bnchdrff thanks a bunch for your solution, it saved the day(s).
@skenan editing the package.json worked flawlessly.
