I have recently upgraded to NPM12.0.1 we have two additional pollers and the following modules Orion Platform 2016.2.100, NCM 7.5.1, WPM 2.2.1, IVIM 2.1.2, NetPath 1.0.1, UDT 3.2.4, VNQM 4.2.4, DPA 10.2.0, NPM 12.0.1, QoE 2.2.0, SAM 6.3.0
We had a little trouble with the upgrade and had to call customer support. We upgraded our primary poller modules to all the newest versions and after we got that finished we moved on to the additional pollers.
This is where we ran into some issues. The additional pollers would not upgrade due to a "version mismatch" it was seeing that the Orion core on the main poller was at 2016.1 and the additional pollers was too far behind to upgrade (i believe it was wpm that it had focused the version mismatch on) we tried everything to get it to work from the new installer that comes with NPM 12.0.1 and individual install of each module but nothing worked.
Talking to SolarWinds Support was kind of a pain this time the rep continued to tell us that we would have to roll back on our primary poller to the previous versions (physical server) and that there was no way to get around this issue.
I didn't really want to roll back that server so we came up with a plan of our own to just uninstall all of the modules on the additional pollers, install the updated modules fresh to the servers. We were not really sure if it would work but in theory it was like losing a server and having to replace it??? right....?
So that went smoothly we got all of our modules installed and the website looked great seemed like everything was working perfectly but we have run into this bug and im not sure if it is related to the way we upgraded our additional pollers
hence the backstory.
On one of our additional pollers we cannot edit interfaces. The website just sits there and spins until it times out and throws this error - Exception of type 'SolarWinds.ApiProxyFactory.TransientApiProxyException' was thrown.
We poured through all of our logs but couldnt find much. I found the below KB Article but i can complete an nslookup with no issue so im not really sure whats going. I have attached a piece of the orion web log that I found suspicious.

Any insight or help with the issue would be much appreciated!!!!!!!!!!!!
