Problem with getting files

[Dian8]

After several successful downloads I'm getting following exception:

Couldn't read the packet length

Trace:

Worst thing is this exception renders session file unusable. All subsequent calls to ConnectAsync() fails with exception "Can't decode packet" Session file must be removed - only after that connection can be successfully established.

Here is also stack trace for subsequent exceptions:

hi , can you implement as describe in this page https://core.telegram.org/mtproto/service_messages#rpc-error , this Can't decode packet this issue removed from telegram web site. i think you must renew your code
