Heroku Dashboard and CLI is facing issues

Deployed my MVP onto heroku (moved for aws eb) last night and having troubles deploying today.

Looks like it's DNS cert. issue, because while trying to change config of my dyno, I got the following response:

ERR_TLS_CERT_ALTNAME_INVALID: Hostname/IP does not match certificate's altnames: Host: api.heroku.com. is not in the cert's altnames: DNS:*.herokuapp.com, ▸ DNS:herokuapp.com

Update:

Web app cannot fetch my active projects anymore.

I can't log in unfortunately. I love heroku, but it does seem like they have their fair share of issues.
