Personal hotspot issue
I can connect my MacBook (late 2013 model) to my inPhone (Xs) via personal hotspot. Previously this has worked with no issues. Now, I can connect, I get the chain link logo at the top of the Macbook Screen, but whichever browser I try (Safari, Firefox, Chrome) it tells me I have no internet connection. The iPhone does have a connection however, through 4G. Why might this have ceased to work?
Mac is OS 11.5, phone is 15.0.
Thank you for any advice.
MacBook Pro 13″, macOS 11.5
