Currently experiencing random Slowness and Timeouts with Foreman v2.1.4

Problem: Currently our Puppet/Foreman server is experiencing intermittent timeouts.
Common issues that we experience are:

Slowness in the Foreman web GUI
Proxy-timeout messages when attempting to access the web GUI
Error message seen when this ocurrs says:
The proxy server received an invalid response from an upstream server.
The Proxy server could not handle thee request.
Reason: Error readying from remote server

Timeout messages when attempting to run the hammer import-proxy command for updating foreman with our Puppet environments along with these frequently occurring errors in the hammer.log file

Currently trying to pin point where the issue is stemming from. I don’t see any useful info in the foreman production.log file and for the most part, I can’t see any glaring issues on the server. The issue seems like it’s almost resource based, but the server itself isn’t running into any bottlenecks.

Any idea where I could get more detailed information from foreman and why it’s running into these issues?

Expected outcome:

Foreman and Proxy versions:
Foreman version is 2.1.4

Foreman and Proxy plugin versions:

Distribution and version:
