IOS phone suddenly loses connectivity to all nodes, what's the issue?

admin

From yesterday evening, both circle X and small rockets did not work, the node was fine, but could not access Google or tg on the computer. I tried the self-built nodes as well as two airport nodes, but they all had the same problem - after connecting to them, it would not allow me to access Google or tg. Initially, I thought this might be related to network issues, but I tested wifi and data usage, and still experienced the same issue. I don't know if it's a setting problem with my phone or something else, any大佬知道的吗?
