Issue can't renew SSL for webmail only

[GlennT]

I host email only on a plesk linux server where website is hosted elsewhere. Previous Let's Encrypt certificate has expired and it was originally configured with HSTS and redirect to https. I can't disable these because no LE SSL is installed so browsers block access.

When i try to issue new LE SSL to webmail.domain.com I get domain not found even though I know it's configured correctly in DNS.

Any ideas on how I can solve this?

Thanks
G

Hello @GlennT
Looks like the issue you faced and ways how to resolve it described here:
Let's Encrypt can not issue certificate for webmail only in Plesk if domain is hosted on another server: An SSL / TLS certificate could not be issued for example.com

If provided solution will not help, could you share the exact error message you getting

Thanks Alapshin. When I change hosting type to No Hosting is there any risk that the email accounts will be deleted?

On a side note, I turned off SSL support but it still remembers that HSTS was previously configured and browsers won't allow access to webmail.

no risk at all, since webhosting files and email stored in different places.

As for disabling HSTS you can try to execute the following command, connected to the server via SSH as root:
# plesk ext sslit --hsts -disable -domain example.com
