RC 5.4.0 no login possible

[CvH]

Since Rocket Chat 5.4.0 you can't login anymore.
Regardless if you use RC Electron Client or normal Webbrowser you end up at a empty screen.

#27480 sounds similar

update

It does not work anymore if OAuth is enabled and "Show Default Login Form" disabled. You need to enable the normal login, if you can use it or not to workaround that problem.

We had the same problem. We had OAuth login only, after reactivating the normal login option on the Admin settings (thankfully we had before the update the session open), it was working again.

it seems a Bug at least for us, when the normal Login is deactivated. Hope for a fix soon :)

[CvH]

we have also just OAuth

[dcardozoo]

If you can, just for testing activate also the normal login. At least so, you can login again

[CvH]

If I enable "Show Default Login Form" at the settings it works again.
If you have locked out yourself this might help #3760 (comment) (not tested if it actually works)

I can confirm this regression bug with version from 5.4.0 yesterday at 17:56 CET. I had to enable Accounts_ShowFormLogin to be able to login again.

I am using SAML login only, this command has saved me several times in the past to enable to login form:

curl --location --request POST 'http://localhost:3000/api/v1/settings/Accounts_ShowFormLogin'
--header 'X-Auth-Token: '
--header 'X-User-Id: N3H9ef5FdjXNX3iRa'
--header 'Content-type: application/json'
--data-raw '{ "value": true }'

sudo snap revert rocketchat-server revert my installation to a working state

I confirm this issue. For us it is critical. The update is not possible until the problem is fixed. We are running 20 instances RC in docker.

[mikesrus]

affected too. saml login not work

[ThibautPlg]

Same here. Thankfully the upgrade to 5.4.0 did not reset the user sessions and we noticed the bug only when inviting new users to the instance.
The workaround works well, thanks @dcardozoo and @CvH .

Before I open a new issue - maybe it's related to this issue:

I've configured OAuth (Keycloak) as a second login source ... all looks great, but there is no additional login button for this on the login screen. Do you see the same behavior in 5.4.0?

@jacotec I was not able to reproduce this =\
