I have a user attempting to connect to a website after logging in she is getting this error.   She had tried multiple browsers such as chrome IE edge.  

Http failure response for https://api.domainname.com:8443/api/oauth/token: 0 Unknown Error

Any suggestion?   She has tried this from 4 different offices from 4 different external IP's

The website host thinks its something on our end I dont think so.

Try the address on your phone and see if it works then, if it works, if your end. Probably a port blocked on the firewall or possibly a VLAN in the way if it's an internal address.

Alex it connects on the phone.  Thanks.   I will have to look at the firewall rules.  Is this 443?

The website connects just fine by the way from any machine.  Its after entering the credentials to login that error is given.

Take that IP off the page please, I have it now.

It's not 443, it seems to be 80 only, there is no certificate on the site either so that's quite a big security risk given what the site is for.

Oh you never said that did you, if it's happening behind the website, it's more likely to be your supplier at a guess.

Ok deleted.  As I said we have 80 opened both ways for http on the firewall and we can connect to the site.   Its after trying to login is when that error is throwing.
