Vaultwarden - Can not send email anymore (STARTTLS error)

[girish]

@mrmx Just tried this and it does work on a new install. Can you go the Location view and click Save without making any changes and then try to invite someone again?

[mrmx]

@girish Done and stays the same, here you are the log:

[2021-11-25 10:23:04.602][vaultwarden::mail][ERROR] SMTP Client error: internal client error: STARTTLS is not supported on this server

Te installation was done a month ago or so, and it's not used until now that we need it. I could reinstall for sure, but I this error can be fixed it would be better for Cloudron

[girish]

@mrmx thanks, just to quickly test, can you install a new vaultwarden instance and see if it has the same problem? If so, this looks like some problem with the new Cloudron 7 update (not sure what that is yet though). In the meantime, I am trying to reproduce this by updating from Cloudron 6.3 to 7 with vaultwarden installed.

[girish]

OK, I did a full test and this works fine for me .

Just to double check, have you configured anything mail related in /app/data/config.env ? If you like I can debug this further, if you write to support@cloudron.io and give us remote access.

[mrmx]

@girish Yep a fresh install works like a charm.
I tried with a previous backup and it's not the the data, so it seems an instance networking problem.

[mrmx]

@girish Nope, I'm sorry but keep the fresh instance and deleted the failing one, so this problem will be in the unknown...

[arshsahzad]

same problem with me...

@girish I have to invite someone, after the recent update of vaultwarden, my SMTP is not working in vaultwarden, earlier it was working, I didn't make any changes, I'm getting below error:-

An error has occurred.
SMTP 5xx error: permanent error (535) - Authentication credentials invalid

[girish]

@arshsahzad are you still facing this issue? Can you tell me which version of Cloudron you are on? I thought we sorted the STARTTLS issues out in Cloudron 7.0.4

[arshsahzad]

@girish I'm using Cloudron v7.0.4 and vaultwarden 1.23.1, When installing the new vaultwarden, it's working fine but the existing vault producing the above-mentioned error.

[girish]

@arshsahzad If you like, I can debug the instance to find out what's happening. Please drop us a mail at support@cloudorn.io. I initially suspected that maybe vaultwarden is caching env vars in the database or something but that doesn't seem to be the case. The env vars explicitly disable STARTTLS and TLS.

[arshsahzad]

@girish I have mailed for support request, with the subject - SMTP Error

[girish]

@arshsahzad thanks, was just investigating. It seems vaultwarden has two sources of configs - env vars and config.json . The latter is editing via the admin/ui interface and overrides the former. In Cloudron package, we use env vars. In your config, I see that SMTP variables are set which means that they have now gone out of sync with the env vars.

I am fixing Cloudron package to use config.json instead of be consistent.

@arshsahzad I have pushed a new package. Can you try now? I already updated your instance.

[arshsahzad]

@girish Thanks for a quick fix, It's now working
