I am accessing a SQL server with .NET MAUI and encountering a TCP transport layer error 35 on my Android phone. This issue does not occur when accessing the SQL server using PC winUI. When testing, I found that read/write access of around 1000 bytes is okay, but when exceeding 1000 bytes, this problem occurs. See the following TCP error image for reference:

    Hello,

    This issue was filed in the SqlServer GitHub repo. See: SQL Server pre-login handshake failed Android 5,6,8.1 #1656.

    You can try to use this workaround from devmartinto fix this issue.

    Best Regards,
