How to add a certificate via vestacp on a port other than 80?

Question

Apache HTTP Server

Installed and configured vesta
Reconfigured the standard port for vesta to be not 80 but 7080
A user with a domain that opens at domain.com:7080 was created in it.
When I try to get a certificate through the vesta admin panel, I get an error

Error: Invalid response from http://<b>domain.com</b>/.well-known/acme-challenge/yNnH3YwcktOz_uDS0h_Qqlusqmn6WpNZcLR6mECLs3U: \

I believe that it should refer to

http://<b>domain.com:7080</b>/.well-known/acme-challenge/yNnH...

Is there a way to force vesta, or rather letsencrypt, to knock on a domain with a port?
