Cooldown issued after failing to join back in time but completed the pug

During the pug, my ping spiked really high and the server was laggy as well for me as well as my teammates. Went to restart once, got late by like 30 secs and was issued a 30 minutes cooldown. Came back, finished the pug but the cooldown remained. Could you clear that up so if by any chance I dc anytime, it doesn’t get stacked! Thanks.
