Starting yesterday afternoon (22 Dec; US west coast), the https://chat.fedoraproject.org URL (matrix web app) results in:
Your Element is misconfigured
Unexpected error preparing the app. See console for details.
The console reports problems with an init.js and an Content-Security-Policy problem.
This is with Firefox. Trying with Chromium had the same result.
Any tips on how to resolve appreciated.
I ended up signing into the default matrix web site and resetting my account there (which uses github for authentication). For whatever reason I was then able to log into fedora server and reset my account. Not sure what was necessary and what was happen stance but I am back in Fedora matrix land.
This problem has resurfaced. It appears that I am effectively unable to access chat.fedoraproject.org. I can log into matrix via my github account.
Installed the element app via flatpak. If I follow the “no encryption” path (no choice), I eventually see the message below. I do not know who the element admin is for Fedora. This is before sign in so there must be a credential cache somewhere?
There was a problem communicating with the homeserver, please try again later.(M_UNRECOGNIZED)
Your Element is misconfigured
Ask your Element admin to check your config for incorrect or duplicate entries.
Homeserver
https://chat.fedoraproject.org
Quite strange. I haven’t seen any other reports of this and it works normally here. ;(
Can you try in a private browser window and/or with a different browser?
Your account looks normal to me from what I can see… if that still doesn’t work, I can ask our matrix provider to look.
Greetings. Thanks for getting back to me. I tested Chrome and Chromium - both work. Firefox is still failing with the “misconfigured” message and javascript errors in the console (both private and normal windows). Interestingly, while in a Chrome session I closed out all other sessions and tried my best to clear out any data/cookies etc in Firefox but still encountered the misconfigured message.
Should I open a ticked with the matrix/element project and see if there is any guidance from that quarter?
best regards
I’m not sure where best to file… perhaps element web folks could track down whats going wrong: GitHub - element-hq/element-web: A glossy Matrix collaboration client for the web.
Does it happen in a new firefox profile? and/or with a new user? Or with firefox started with –safe-mode (which would point to some extenstion being the problem).
Thanks for the suggestions. Both safe mode and a new profile result in the same error. I also get the same error on a different profile where I did a refresh for firefox. I will try with a ticket on the element-web github repository.
Many thanks for checking
By happenstance I used firefox to log into chat just now - and I was directed into the log in process which succeeded. Not sure what was changed or where (if anything), but I this is no longer an issue. Many thanks @kevin .
Odd. I did not do anything here. 
But glad it’s working for you.
