Project Server URL

[CojoUC]

Hello!

I have created a Web Application on HTTPS Port 444 for DNS
dnsname.company.com. Additional we have a F5 Load-Balancer in place
were we have added the URL.
I have 2 Alternate Access Mapping for the Default site

Internal https://dnsname.company.com Public
dnsname.company.com
Internal https://dnsname.company.com:444 Public
dnsname.company.com

When I now try to access the Project server instance via
https://dnsname.company.com/instance I cannot connect and will be
forwarded to https:// dnsname.company.com:444/instance. When I type
https:// dnsname.company.com/default.aspx everything is fine.

Do you know why I will be forwarded to the :444 URL when I do not
enter the default.aspx?

Thanks for your help.
