Sucuri Page Timeout Issues

Hello -

I currently use name cheap VPS Quasar as my host and for years now (a decade) I have used Sucuri. However, we've been encountering some problems that have our host and Sucuri pointing figures at one another.

People will receive the timeoutpage (that has the Sucuri graphic). I have sent screenshots to them and they have told me they are on blacklisted IP Addresses. These are general public consumers using ISPs like Comcast or Verizon. So, I'm a bit baffled.

Additionally, the site will timeout - there won't be page that comes up. It's just blank.

When communicating with Sucuri, they tell me our web host is timing out according to logs.

When I go to name cheap with this information, they tell me the server has passed all tests and they have no indications of time-outs. They have asked me to get the logs from Sucuri so they can know more specific information.

So far, Sucuri has not responded with the logs that say the server is timing out. They have ignored the request keep looking for malware which ends up being clean

namecheap has suggested we turn off the Sucuri firewall so they (name cheap) can run diagnostics on the server and find out if it is timing out. However, with no firewall, I am concerned about the legitimate traffic that was shutting down the server to begin with (causing me to get Sucuri) will reappear.

Looking through several posts, this seems to be a common theme with Sucuri. However, the price increase to go to Wordfence is quite a bit.

Thoughts? Suggestions? Should I do as name cheap suggests and turn of Sucuri's firewall and see what happens?
