Miners stopped being added

[kronxg]

I have a proxy, 3 months ago I quickly assembled a database of 1k miners in a proxy. Then I felt some kind of ceiling and could not get more than a thousand. Then I found out that you can increase the number of miners in the proxy. As a result, everything is going very badly for me so far, miners are simply not being added. I'm clearly missing something, my traffic is very good, the number of miners is growing poorly, although I see that miners are launching very well. What could be the problem? I use a proxy from aeza
