I have a [vb.net](http://vb.net) project which has been running for 10+ years. Recently users have been reporting that new tiles are no longer being downloaded. Saved tiles work fine. We experienced a similar issue in about 2020 and that was caused by a ‘new’ requirement that a user\_agent needs to be set. Since we changed that the program has worked without any problems. Are there any new requirements for downloading tiles?

fyi We are using v4.8.6 .

Any assistance will be appreciated.

Thanks

Mike
