I had this issue today with a different solution...
I could access TM1Web URL from the local server, but not from remote servers. Also, even TM1Web on the local server could not pull up a PA Service Instance to log into (which is hosted on a different server).
Because I could ping the servers successfully but can't communicate to the specific services, I figured it had to do with the ports - and in fact it did. In a working instance, the Windows Firewall had inbound and outbound port rules called "IBM Planning Analytics." Our failing server had no such rules. As such, we created an inbound and outbound rule on every server hosting PA software.
This link about blocking/opening ports was easy to follow:
https://www.thewindowsclub.com/block-op ... 8-firewall. Basically we searched "Windows Firewall," got to advanced settings, and "Add new" rules for both inbound and outbound.
Add new
> Port
> TCP
> Specific Local Ports: we put in every PA port we know, but I don't know what actually is required for the different components to speak to each other. e.g.: 5495, 5498, 9510, <tm1 service port>, <tm1 service http port>
> Allow the connection
> Apply rule ... you decide, but we selected all Domain, Private, and Public. The server will only ever be connected to its corporate domain
> Name: IBM Planning Analytics, or w/e
Please correct me if I'm not implementing best practice above. I'm not an IT person. I just get by.
