NIFI failed to register flow with Flow Registry due to Read timed out

[#1]

Recently, we have started experiencing issues with our NiFi commits in the NiFi Registry failing due to read timeout exceptions. The error message displayed is "Failed to register flow with Flow Registry due to Read timed out." However, despite this error, the commit in the NiFi Registry is actually successful. We are using the Git flow provider on the NiFi Registry side, and I can see a commit after every attempt, despite NiFi showing a timeout error.

Has anyone else encountered this issue, or does anyone have suggestions on how to resolve it? Any help would be greatly appreciated. Thanks in advance!

Here are the complete logs of exception:
