Strange hostbill behaviour - some fast wifi locations hardly load the page

[andika]

Hello,

I have noticed some strange behaviour of hostbill. When I'm on any of my offices the client area area / admin area loads normally fast but when I connect from some hotel wifi or any wifi connection other than my offices it loads in many seconds like its checking for something or like the server is overloaded. The wifi connection I connection from are extremely fast so its not related to ISP for sure.  Why is this happening ?

Hi,

When does this happen - when you are logging into client/admin area or after you are logged in?

Thanks.

The main cause of this symptom is missing or incorrectly configured reverse DNS (PTR records) on the client's IP address.
Hostbill does a reverse-dns check upon login and if for some reason the IP does not return a valid PTR or the related nameservers do not respond at all, Hostill will wait for a predefined PHP timeout. In default setup you should have similar issues when connecting from those locations to your SSH or mail server as those generally by default have reverse DNS configured.

To confirm, get your public IP and run the command "nslookup YOUR.HOTEL.WIFI.IP" on the server Hostbill runs on. If it doesn't return within a split-second with a valid answer (NXRECORD is a valid answer too!) then you have your issue.
