Unable to update parameter context

Hi,

we run 5 nodes cluster on our on-prem system and recently we spotted an issue with updating Prameter Context. We can't modify values or add new key, val pairs while adding new Parameter Contexts works. Even if given PC is not assigned to any process group if fails to be modified. It also happens on our nonprod and dev clusters which are in different networks. I will be glad to give more details but I'm not sure what could cause this situation.

From UI we can see that it fails while updating state of Controller Services- we also tried to disable all controller services first but it didn't help. I also attached log error message.
