Can't save portal config in ArcGIS Server Manager

[MKF62]

Whenever I try to edit the URLs in this dialog box and click "Save," the dialog box does nothing. It doesn't save or close. I am putting in the URLs like this:

Portal:  https://mywebsite.com/myPortalwebadaptorname 

Server: https://mywebsite.com/myServerwebadatorname/rest  

In addition, I have tried:

For the portal URL, put "/home" after my Portal web adaptor name.

For the server URL, I've tried leaving "rest" off the end. I've tried making it my server CNAME:6443 and my FQDN:6443 instead of my website with "/arcgis" at the end and also "/myServerwebadaptorname" instead. 

None of this works. The save button does not seem to function. Anyone else have this issue? I've logged in and out of the server manager too.

The solution was to use a different browser. I was originally using Chrome, but switched to Firefox and it saved. Oddly, when I opened back up Chrome the saved URLs had persisted (like expected), but I decided to change the URLs again just to see if the save button now worked in Chrome; it did. Makes no sense, but it worked for me.
