I did not use TLSharp, but according to its documentation you need to update the data center address in the TLSharp.Core.Network.TcpTransport.csfile provided by the TLSharp library.
:
I get an error MIGRATE_X?
You should change the telegram server address to X. X server address you can get from InitResponse or from Server addresses list. Address should be changed in `TLSharp.Core.Network.TcpTransport.cs`
Server addresses:
Server 1: 149.154.175.50:443
Server 2: 149.154.167.51:443
Server 3: 149.154.175.100:443
Server 4: 149.154.167.91:443
Server 5: 91.108.56.165:443
, TLSharp.Core.Network.TcpTransport.cs, 91.108.56.165, .. server 5.
