ACME certificate PHP Fatal Error

[Gertjan]

@jimp said in ACME certificate PHP Fatal Error:

When you leave it blank it defaults to using DoH/DoT queries to cloudflare and quad9 IIRC

Aha ... the log tells me just that : it's the local acme.sh that is checking regularly - like some kind of 'active waiting'.
And when found, then it informs Letencrypt to do the file domain name zone TXT verification.

If a local policy forbids DoH activity then 'acme.sh' will fail.
