I don’t know what to do

I was playing ranked and sometimes during my matches my game crashes and I reconnect and all is good. But today it happened and I tried to reconnect and it says I’m banned for 15 mins for disconnecting even though I didn’t choose to disconnect and know those 11 ppl are gonna avoid me/report me for throwing even though I didn’t leave on purpose. I don’t even know if I wanna play ranked anymore cause I’ll get banned again. Any help would be appreciated

I’m on pc and already put the setting on low.
