Http request error: Post EOF


I am seeing this error, every now and then. This is resulting in packet loss as the post request is not successful.
I am not sure why this is happening. The endpoint to which it is supposed to post is definitely a valid ip and url.

This behavior is particularly seen when I am using 915 frequency band.
