Can I get some more detailed information about Credit Card? When we can get them? What is the status for now?

Hello, i have a big problem with Claymore Miner Manager. I have about 150 rigs in my network. Most of them works with Ethos - some of them with miner version 11.6 some with 11.7 or 11.8. A lot of miners after about 20h stops sending stats on port 3333. I get information on Claymore Manager that rig is not working (same in Awesome miner - i use both solutions), but rig works normally. I found that was a problem with version 11.6 on Linux and there is some fix for them, but i hav this problem also with 11.7. Do you have any solution for that?
