Timeout during connect (likely firewall problem)

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. crt.sh | 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: sso.smartidentity.nicotechnologies.com

Hi @sekulu,

It looks like some part of your network doesn't permit incoming connections from the rest of the Internet. In order to complete this verification, you have to be able to receive incoming connections on port 80, which currently seems to be blocked by a firewall or something.

the problem was with my AAAA records. this has been resolved
