1. The problem I’m having:
I’m trying to run a caddy server via docker compose with the basic auth option but getting illegal base64 data. The docs say that caddy expects a bcrypt hash instead of a base64 string as the value but it keeps complaining about base64. So confusing, it must be something wrong on my end but I can’t figure it out.
2. Error messages and/or full log output:
run: loading initial config: loading new config: loading http app module: provision http: server srv0: setting up route handlers: route 0: loading handler modules: position 0: loading module 'subroute': provision http.handlers.subroute: setting up subroutes: route 0: loading handler modules: position 0: loading module 'authentication': provision http.handlers.authentication: loading authentication providers: module name 'http_basic': provision http.authentication.providers.http_basic: base64-decoding password: illegal base64 data at input byte 0
3. Caddy version:
caddy:2.4.6-alpine
