Can't login to admin console

[RedOrion]

I have configured my email settings as below and them and getting errors when I try to login to the admin console. It was working fine till I changed my smtp settings. I can ping the mail server from the host no problem.

globalSettings__mail__replyToEmail=services@mail.com
globalSettings__mail__smtp__host=mail.mail.com
globalSettings__mail__smtp__port=587
globalSettings__mail__smtp__ssl=false
globalSettings__mail__smtp__startTls=true
globalSettings__mail__smtp__trustServer=true
globalSettings__mail__smtp__username=services@mail.com
globalSettings__mail__smtp__password=<password>
globalSettings__disableUserRegistration=false
adminSettings__admins=services@mail.com

It seems like it cannot connect to mail.mail.com. Is mail.mail.com a proper SMTP endpoint?

It is. It has proper MX records, etc.

Maybe related to this: dotnet/runtime#1488, seems there are some issues with DNS resolution and intermittent failures with this similar exception stack on dotnet core on linux.

Hi @RedOrion,
We're cleaning up our repositories in preparation for a major reorganization. Issues from last year will be marked as stale and closed after two weeks. If you still need help, comment to let us know and we'll look into it.
Thanks!
