The server could not connect to the client for DV

1

As the titles suggests LE is having issues connecting to my webserver, however I can find no issue. DNS points to the correct spot, and files are accessible in that directory.

LE appears to futz around with nonces for a bit, saves the chellenges (i see no evidence in the log to the contrary), starts the challenge and fails ambiguously with the error stated in the title.

I cannot find any of the issues in previous topics about this error to apply to my situation.

Can you post the command used, the last part of the log files, and your domain name please?

./letsencrypt-auto certonly -a manual -d strato.im -d www.strato.im -d git.strato.im -d jira.strato.im

./letsencrypt-auto certonly -a webroot --webroot-path /var/www -d strato.im -d www.strato.im -d git.strato.im -d jira.strato.im

And the error for both:

Hum. That was working before now it’s broke again, one moment.

Alright I can connect via external services fine now

Okay, somehow the letsencrypt standalone webserver necroed listening on that port from trying that before and it’s working now!

Thanks
