My google playstore keeps saying no internet connection. It works with mobile data but not wifi!

I have a lg g5 or Lg-F700S. I recently updated my phone to android 7.0. Since the past week my playstore does't work. I have tried restarting the phone, clearing the data and cache. My date and time is set correctly as well. I did a factory reset it didn't solve the problem. I uninstalled the playstore and reinstalled it. I also removed my google account and re-added it. Moreover the playstore works over my mobile network, it specifically doesn't work with my wifi. I don't know what to do.

Welcome to Android Central! Does it work on any other wi-fi network? Is the problem only with your home wi-fi?

I have come across the same problem. Mobile data is OK, but if I choose WiFi only Playstore tells me I have no internet connection.

I have a Huawei Mate 20 Pro.

I have tried clearing the cache and turning on background data, but this has not helped
