TLS connection error with OTP 25 about tds

[bosko]

@moogle19

Elixir Version: 1.13.4-otp-25

MSSQL Server Version: Azure (MS SQL is on Azure, but since it is out of my control I am not sure if it is Azure MS SQL or is it installed on VPS there)

Ecto repo configuration:

port: 1433,
ssl: true,
timeout: 30000

Even though this probably does not cause this problem I have to mention that firewall is active on Azure and allows connection only from certain IPs. Of course, connection works from those IPs from Elixir 1.13.0-otp-24.

It does resolve the problem. I've checked both TDS versions 2.3.0 and master branch and both work.

No additional ssl_opts are set.

Could you specify the following:

Elixir Version:
MSSQL Server Version (2016/2019/Azure?):
Additonal configuration in (without host / user stuff):

@bosko
There was a new release of OTP just now (https://github.com/erlang/otp/releases/tag/OTP-25.0.1).
It contains some fixes regarding SSL handling.

Could you try 25.0.1 to check if this resolves the problem?
