Hi there. I would like to enable REST API, but so far i got 404 while trying to access: http://mykoha-intra.mydnsname.org/api/v1/.html http://mykoha.myDNSname.org/api/v1/.html I enabled below options: OPACBaseURL => http://mykoha.myDNSname.org OpacPublic RESTBasicAuth RESTOAuth2ClientCredentials RESTPublicAnonymousRequests RESTPublicAPI I see below errors in '/var/log/koha/mykoha/plack.log': 172.17.0.1 - - [26/Mar/2021:04:42:52 +0000] "GET /api/v1/app.pl/api/v1/.html HTTP/1.1" 404 - "-" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" Many thanks in advice.
