After a few months working fine, i cant connect to the bulb anymore

When following the steps, either on yeelight or mihome, the wifi “yeelink-light_xxx” doesnt show up, instead this appears below the wifi list, it says “Setup a New Device”

When i click it, it does go through and connects my phone to an wifi with the same name as seen above but when i return to the app nothing happens, its just stuck.

I had it working fine for almost 2 months, and this week for some reason i had to reconnect to the bulb and this is happening. I dont think i changed anything that could have caused this, no changes to wifi, to the bulb, to my phone etc
