Backend is offline (network error) after upgrade to 0.14.2

[elronn]

Hi !

After upgrade my RMM to 0.14.2 version. The upgrade went well but i have this message when i try to login.

If i check the dev tools i have this message

Blocage d’une requête multiorigines (Cross-Origin Request) : la politique « Same Origin » ne permet pas de consulter la ressource distante située sur https://api.ajc-info.fr/checkcreds/. Raison : l’en-tête CORS « Access-Control-Allow-Origin » est manquant. Code d’état : 405.

Can i try to restore my last backup (in 0.13.4 version)

Thanks for your answers

You can restore your backup.

Can you also translate the error?

the error in english

Blocking a Cross-Origin Request: The "Same Origin" policy does not allow you to view the remote resource on https://api.ajc-info.fr/checkcreds/. Reason: The CORS header "Access-Control-Allow-Origin" is missing. Status code: 405.

do you have any proxys or anything custom on it?

400 errors are logged, look at the logs for more details.

Why/where did you get that API url from?

Gives me an error here.

Gives me a different error between your server and mine. mine returns proper API returns.

Yours gives what looks like rmm. Error pages

I have the same problem after a fresh install.

Access to XMLHttpRequest at 'https://api.DOMAIN.TLD/checkcreds/' from origin 'https://mesh.DOMAIN.TLD' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Looking at the documentation, https://docs.tacticalrmm.com/troubleshooting/, there is a paragraph for CORS errors. My computer does ping the correct IP for all 3 subdomains. I am using cloudflare but I am not using a proxy. Reading this did not help me: https://developers.cloudflare.com/cache/about/cors/.

Like the OP new VM, and retry the install logged (see docs).

If you're still having problems create a new thread as this thread was resolved by reinstall and wasn't doing cloudflare something.

Fixed by reinstalling.
Thanks guys, you rock. Better response time than fortune 500 companies hahahaha.
