Tuya Integration - No Devices and connection blocked to iot.tuya.com


I am having a rather strange issue since last night where I noticed that my tuya integration in my home assistant setup no longer holds any devices. After I tried to then open iot.tuya.com in my browser I noticed that I was not able to open or connect to iot.tuya from my home network. So I tried my mobile data and through that I was able to visit iot.tuya.com. It seems like my home IP address got banned or something? Did anyone else ever experienced this before? (tuya tech support is not very helpful)

edit: some testing i did:

thank you
