Rocketchat loads a blank grey screen

[Sam_uk]

My Rocketchat instance doesn't load in Chrome/Firefox on MacOS or Debian and I have user reports of it not working in IOS. Windows users seem unaffected.

Dunno if the log below helps? Restarting the app doesn't fix it.

This is what pingdom says: https://tools.pingdom.com/#5f604c6b14000000 it seems to be running on some level?

Anyone got any ideas? What other logs could I look for?

I can confirm I also only see the gray page while visiting, however there are no request failing nor any other error message shown on the client side.

Is there any chance you may have tweaked some css or templates, which might interfere here?

[Sam_uk]

@nebulon Thanks, no changes to CSS that I'm aware of.

[nebulon]

@sam_uk have you set the loglevel to be 2 - Errors, Information and Debug in the admin view -> Logs ?

[girish]

I see an interesting request to license:isEnterprise which I don't see in our rocket.chat instance. Did you change any license setting?

[william]

I'm having the same issue. Chrome Dev Tools shows multiple failed fetches (requesting an insecure resource) and a ton of missing modules.

[girish]

@william can you paste what you see in dev tools ? Is this a new installation ?

[william]

@girish

I've been running RC for several years, and migrated from Snap to manual 17 months ago.

Here is the first screenful:

[william]

@girish

I noticed the Site URL in the Node banner was "http://" rather than "https://" so I manually updated the Site_Url in rocketchat_settings (in Mongo) and restarted RC.

Now it works.

I'm left to ponder: was it always missing the "s?" If so, why did it work until I upgraded? If not, why did it change? rocketchat.service has always set ROOT_URL to https...

[Sam_uk]

@nebulon Where should I set the log level please? I had a look through the Cloudron dashboard & Rocketchat menus in Cloudron but I couldn't spot this setting.

my.rocketchat.org/admin level stuff is obviously inaccessible to me at this point.

No, but we have connected it to https://cloud.rocket.chat/login to try to get push working.

[Sam_uk]

@sam_uk The other thing we have been doing recently is trying to connect the Rocketchat API to N8N. May be unrelated, but worth mentioning.

[nebulon]

@sam_uk ah of course you can't login to the admin UI. So open a webterminal into the app and click the mongodb button. Within the mongodb shell run this command:

db.rocketchat_settings.updateOne({"_id":"Log_Level"}, { $set: { "value": "2" }})

Since you mentioned n8n, if that may cause issues, you can probably also search for the settings values related to this if any with:

db.rocketchat_settings.find({})

then it to page through all settings, I don't know how the n8n ones are called though.

[Sam_uk]

@nebulon said in Rocketchat loads a blank grey screen:

db.rocketchat_settings.find({})

Thanks, I've updated the logging.

[Sam_uk]

@sam_uk OK I've fixed this. It looks Iike I/someone had disallowed anonymous read in the settings. So it was fine when logged in, but as soon as you log out it breaks.

[nebulon]

@sam_uk this is great! Although I don't fully understand why such a setting would essentially render rocketchat unusable. Maybe worth reporting upstream?

[Sam_uk]

@nebulon Yes, I did open a thread on the Rocketchat forum, I'll update there too.

Thanks for your help on this.
