App help keeps losing connection in wifi android phone

Hi Reddit,

I just changed my ISP and when on my wifi I get multiple messages that Reddit is having trouble connecting. very few videos will play. if I go to mobile data the connection is fine. switch back to wifi and it works for 5 or so minutes then drops out again.

no problem on any other networks just my new home ISP.

deleted and re installed the app restarted my phone multiple times. have rebooted my home network multiple times.

hopefully the right section to post, any help would be great
