Hey guys noticing some weird behavior after the last update. @girish

1. Connection timeout on API refresh
2. all connected apps firing outbound email with SendGrid are failing
3. 0 sending after update on Wednesday morning

. . . did you mean to leak your API Token?

Is the Email Status ok? Second, can you try sending test email - https://docs.cloudron.io/email/#send-test-email

[affinity]

@BrutalBirdie its brand new and only a fraction of the full string. no worries

[affinity]

@joseph this works surprisingly but the outbound relay is failing for all internal emails. And nothing is able to send from any email or app. Restarting does not do anything. This went out on the last patch v8.3.2

@affinity are you sending to sendgrid via port 587? and are you using digitalocean servers?

DO seems to have blocked outbound port 587 for some strange reason (we got some reports about this). You should try telnet smtp.mailgun.org 587 . Does it connect ? If it doesn't you have to ask DO support why they blocked it.

@joseph yes... i have Digital ocean. I don't have a mailgun account so I cant test that. They already have port 25 block but thats why we have sendgrid to get around that.

[affinity]

Okay, this is solved. Using port 2525 as an alternative seams to get past this current block... but i have reached out the DO as well. Thanks for helping!

@girish Just a suggestion it would be so much better to have the ability to set outbound providers credentials globally and then just bind/link them on the domain level. So in the event of an API refresh or in the case a port change, i dont have to go through hundreds of apps (in my case) manually update the effected field one by one..

@affinity @girish as in set them a global profile which then get picked up by any apps via ENV VARs?

Then you'd just need an app restart.
