I having trying to add a CNAME provided by firebase with my domain provider (strato) without success.It is somethign like
CNAME _acme-challenge_hsfgdhsdhghdsd.mydomain.com.
VALUE xxxxx-f64df44d13333.10.authorize.certificatemanager.goog.
I cannot use this CNAME with my domain provider. It seems to be too long. I have tried _acme-challenge_hsfgdhsdhghdsd without success.
The only one that works is _acme-challenge but I don’t know if this is correct.
