Rocket.Chat flashing display

Link to the old thread where I originally reply: Rocketchat nur wild blinkendes Bild

Thank you for reply.

I read also the german thread: yesterday I removed (apt purge) rocketchat, delete the folders created in /etc e /var/lib, delete the volume created by rocket chat (docker volume rm egroupware-rocketchat_mongo) and also did a “docker system prune” and a “docker volume rm $(docker volume ls -qf dangling=true)”.
With a clean installation (apt install egroupware-docker + HTTP_HOST=myhost /etc/egroupware-rocketchat/install.sh) https://mydomain/rocketchat is active (in lan and in internet) but the problem reappears (with any browser firefox chrome and any SO Linux, Android, Windows).

The database of eGroupware is not in a container, but seems the installation logs don’t report error with this configuration.

Here the active container:
docker container ls

Later I send the requested logs.

The configuration log

rocketchat.txt2 (72,1 KB)

where there are a couple of warnings:

• LocalStore: cannot set store permissions 0744 (EPERM: operation not permitted, chmod ‘/app/uploads’)
• (node:10) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

I upgrade RC to the 3.15.3 revision
https://hub.docker.com/r/rocketchat/rocket.chat/tags?page=1&ordering=last_updated4

with this instructions

and the page don’t flash. As soon as I completed the setup I’ll send another reply.

I tested the 3.15.3 versions and the installation, admin login and setup wizzard gone all right.
The admin user login regulary with username and password.
I also setup all the option requested here:

and here

but I still have an issue when direct login the RC link in eGroupware, with the oauth autenticated users: it open the iframe of RC, but can’t login (the page continuously reload).

I find this error message in the RC log:
I20210709-17:32:02.523(0) Exception while invoking method ‘login’ Error: Failed to complete OAuth handshake with egroupware at https://myurl/egroupware/openid/endpoint.php/access_token. failed [401] {“error”:“invalid_client”,“error_description”:“Client authentication failed”,“message”:“Client authentication failed”} at CustomOAuth.getAccessToken (app/custom-oauth/server/custom_oauth_server.js:148:18) at Object.handleOauthRequest (app/custom-oauth/server/custom_oauth_server.js:205:26) at OAuth._requestHandlers.

Maybe the setup of oAuth is different in this version (there is some additional information in the module setup): maybe I find a solution tomorrow.

Thank you very much Stefan and thanks to all the developers for the fantastic project.

Unfortunately I did not found the solution. The setup gone all right with the default options (just copy the Egroupware oAuth secret and users accounts get loaded), but when a user try to open the Rocket Chat tab in eGroupware, he can’t login: the frame continous reload. iframe setting are correctly setted.
Only the admin user can login, but only using the external url https://mydomain/rocketchat/ and manualy insert user credentials.

I tried with Firefox and Chrome, either in windows, linux (only firefox) and android. The users was automaticaly added as user in rocketchat, we have a green dot in the right users bar, but if you try to send a message to another user, you cannot open the frame (iframe options are setted up). There is a login problem in open-id. See the below log.
We use a TWO FACTOR login, maybe it’s helpful.

We have identical configuration.
