Whatsapp calling stopped working over wifi, gets stuck on "connecting..". It works ok on mobile data
Setup: Fibre box > Deco S7 home mesh wifi (includes 3 unit) > All devices
Background and Issue: I have been using above setup since a year, I never had any issue on whatsapp calling. since last couple of days, whatsapp call (Video/audio) gets stuck on "Connecting.." and it never connects over wifi. All phones on my network have this issue, I have checked mine (Android) and my partner's (Android) phone, only whatsapp calling when used over wifi not workin, over mobile data it works normal.
Troubleshooting tried:
- All general steps (reopening apps, re-added wifi network, rebooted wifi and fibre box, got ISP to reset network, cleared whatsapp cache, reinstalled whatsapp, reset network settings, restarted phone couple of times, all apps and firmware is updated) - no change
- Tried to add port forwarding - no luck (may be I'm not setting up correctly, but when I tested using Deco's open port checker, it never comes as positive)
Can someone please help me get whatsapp calling work again?
