Portal Web Adaptor Configuration Spins

[cdevault_pickett]

I'm in the middle of upgrading a Portal from 11.2 to 11.4, Portal successfully installs and runs. However after I uninstall the previous web adaptor and install the new web adaptor I get to the configuration page and it never seems to configure and just sits there and spins. 

I am using the correct administrator credentials. I have tried various FQDNs of my portal machine (the web adaptor is installed on a separate web server). Using IIS on Windows Server 2016.

• machinename.domain.local
• https://machinename.domain.local
• machinename.domain.local:7443
• https://machinename.domain.local:7443

This is the second time I've made it to this point and cannot get any further. There's no errors or anything. Does anyone have any ideas?

Remove your browser from the equation and do it via cmd line.

I gave it another shot and it worked. Not sure what happened there, but like my notes said, "Patience is key" as it did take a long time. The server web adaptor took 2 seconds...

The Portal web adaptor configuration has always taken much longer than the server web adaptor for me. One thing I noticed is that when it is configuring, the antivirus program in task manager spikes up in CPU/RAM usage. And when antivirus is disabled, the configuration is much faster. Other people have recommended to disable antivirus during upgrades and that it will help it go faster.
