Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: eravo.fr
I ran this command: Open SSL installation, SSL installation with retrieval of the "_acme-challenge" TXT.
Added SSL in Nginx Proxy Manager and found the certificate.
It produced this output: If I go to https://nginx.admin.eravo.fr/, I get an error "ERR_HTTP2_PROTOCOL_ERROR", while in http://nginx.admin.eravo.fr I get "Congratulations"
