Stale OCSP response and "unable to write OCSP staple file" error #6524
Description
I'm running Caddy with TLS by reusing certificate obtained externally with acmetool:
{
auto_https off
}
https://:8443 {
tls /var/lib/acme/live/example.com/fullchain /var/lib/acme/live/example.com/privkey {
}
// ...
}
After a while, Firefox stops opening the site, citing stale OCSP response. Restarting Caddy fixes the problem. Reloading doesn't help.
I noticed the following error in the log file, which might be related to the problem:
{"level":"error","ts":1723840048.373416,"logger":"tls.cache.maintenance","msg":"stapling OCSP","identifiers":["example.com"],"error":"unable to write OCSP staple file for [example.com]: mkdir caddy: not a directory"}
