This work for me. Once logged on, you can turn Enable LTE on again. Things should be fine.
This had been discussed before. You would actually need to enable data again before logging in since such actuvity would require an internet connection. This likely has to do with a specific IP address being banned. It's not really about disabling LTE specifically, but more about disconnecting from the internet and the reconnecting to get a new IP address. Disconnecting only LTE probably bumped you down to the HSPA network which resulted in the same.
