I try to install Traefik with Lets Encrypt by using this manual Traefik 2 Basic Configuration
My VPS allow 80 and 443 ports and they are open.
When traefik try to get certs the ssh terminal is waiting and nothing happens. I used letsdebug page and got this message:
[ANotWorking] ERROR domain.com has an A (IPv4) record ($IP address) but a request to this address over port 80 did not succeed. A timeout was experienced while communicating with domain.com/IPadress: Get "http://domain.com/.well-known/acme-challenge/letsdebug-test": context deadline exceeded Trace: @0ms: Making a request to http://domain.com/.well-known/acme-challenge/letsdebug-test (using initial IP address) @0ms: Dialing IPadress @10000ms: Experienced error: context deadline exceeded [IssueFromLetsEncrypt] ERROR A test authorization for domain.com to the Let's Encrypt staging service has revealed issues that may prevent any certificate for this domain being issued.
