Is AikaPool stable? I can rarely enter the site, it usually tells me connection timed out or it refused to connect. And I can almost never connect to the mining pools.

I have set up CGMiner 3.7.2 and have tried it on several pools. First I tried AikaPool and have successfully mined some XVG, but I can't connect to it anymore for some reason, so I tried MiningPoolHub and TheCoin. On both of those pools my miner seems to be working fine, but my workers don't show up as active and I don't see any hashrate on the dashboard. Very confused.

I got version 3.7.2 of CGMiner. I followed these instructions: https://aikapool.com/xvg/index.php?page=gettingstarted
After fucking around with it for a while, I just couldn't get it to work, so I tried different versions and had no luck with them either. Finally, I gave one last attempt at making version 3.7.2 work and it did. I wanted to see if it would work if I closed it and opened it again and no it doesn't work anymore. Just gives me this: https://imgur.com/a/4QHi4
I'm using an AMD Radeon 280 if it even matters...
