Rejecting connections. 
Hi, I have had this problem for over a year with proxy. After 3/4h of mining, xmrig-proxy stops accepting new miner connections if it reconnects, also API stops responding. In simplified, proxy can't accept any sort of new connection (API, miner) after 4/5h of mining. Miners already connected continue to mine but if I restart miners or do something, Proxy does not accept them and API is unreachable. After restarting Proxy, all go back to normal, and after 4/5h it breaks again. Please fix the problem, it is an Xmrig-Proxy problem because I've tried: 
-Different OS (CentOS/Debian) 
-Open Files Limit increased
-Swap file activated
-With TLS/noTLS (pool/miners)
-Keepalive on/off (pool/miners)
-Different Pools, coins, algos
