I am getting this error below. Not sure what's exactly causing it, but seems that the the SQL Server doesn't support ssl version the driver requires.

[david-puglielli]

@Afroty The latest ODBC driver (version 17.4) fixes some issues with SSL, although we haven't seen that error before. Please check if you are using the latest one and upgrade if not (instructions here). Also, what version of the sqlsrv drivers are you using?

[aaly00]

@david-puglielli
I think I am using the latest version. I attached my dockerfile as well as my docker-compose.yml to the issue.

[david-puglielli]

You would be getting the latest ODBC driver and sqlsrv drivers then, but none supports SQL Server 2008 unfortunately. If upgrading SQL Server is not an option, then you can try rolling back to a previous version of the ODBC driver using the instructions here (you may need version 13.x of the driver, for which instructions are further down the page).

[aaly00]

But version 13.x is not compatible with debian 10 ?

[david-puglielli]

Actually SQL Server 2008 SP4 does support TLS 1.2 - see here.

Also there a number of known issues with openSSL and Debian 10: https://wiki.debian.org/ContinuousIntegration/TriagingTips/openssl-1.1.1. This may require a configuration change - see #1021 and this comment. Please try that and let us know if it works.

[aaly00]

@david-puglielli . I did try that but it didn't work.

[aaly00]

Downgrading the minimum to TLSv1.0 actually worked, but it is not a permanent solution. I changed /etc/ssl/openssl.cnf section [system_default_sect] to

[system_default_sect]
MinProtocol = TLSv1.0
CipherString = DEFAULT@SECLEVEL=1

[david-puglielli]

Have you upgraded your SQL Server with TLS 1.2 support from the link I provided? The update is available here.

[aaly00]

Unfortunately that is not possible for now.
I'll close this since msphpsql is not the cause for the issue.

[lmtam]

hi @Afroty , Did you fix this issue? if yes, can you help me fix it?

[aaly00]

@lmtam
Yes. You could upgrade you SQL Server as @david-puglielli mentioned, or you could downgrade openssl minprotocol and CipherString.

if you are using debian. You can add this to your dockerfile which should fix the file. Understand, however, that there is a security risk with this.

RUN apt-get update -yqq \
    && apt-get install -y --no-install-recommends openssl \ 
    && sed -i 's,^\(MinProtocol[ ]*=\).*,\1'TLSv1.0',g' /etc/ssl/openssl.cnf \
    && sed -i 's,^\(CipherString[ ]*=\).*,\1'DEFAULT@SECLEVEL=1',g' /etc/ssl/openssl.cnf\
    && rm -rf /var/lib/apt/lists/*

[lmtam]

Thanks. I upgraded the SQL Server and fixed this issue.

[go-xmyang]

@lmtam
是的。您可以按照@ david-puglielli 所述升级SQL Server ，也可以降级openssl minprotocol和CipherString。

如果您使用的是debian。您可以将其添加到应该修复该文件的dockerfile中。但是请理解，这样做存在安全风险。

RUN apt-get update -yqq \
    && apt-get install -y --no-install-recommends openssl \ 
    && sed -i 's,^\(MinProtocol[ ]*=\).*,\1'TLSv1.0',g' /etc/ssl/openssl.cnf \
    && sed -i 's,^\(CipherString[ ]*=\).*,\1'DEFAULT@SECLEVEL=1',g' /etc/ssl/openssl.cnf\
    && rm -rf /var/lib/apt/lists/*

This is very useful to me.

[unvaare]

@Afroty I am facing similar issue on CentOS7, any idea how can I fix this on CentOS? This happens when I am running MS SQBL ODBC driver using a dot net core app that connects with MS SQL Server using ODBC and then disconnects. It connects in first iteration it works but after that it gives SSL Provider error.

[Razorhunter]

I'm getting the same issue after upgrading to Ubuntu 20.04 Beta...first, it worked on 19.10...but after upgrade ubuntu distro, it prompt me the error.By the way, I'm not using docker

[yitam]

@unvaare please check with the folks at dotnet/runtime instead

@Razorhunter please create a new issue with details of your server, client, etc. You can refer this issue

[ludufre]

Downgrading the minimum to TLSv1.0 actually worked, but it is not a permanent solution. I changed /etc/ssl/openssl.cnf section [system_default_sect] to

[system_default_sect]
MinProtocol = TLSv1.0
CipherString = DEFAULT@SECLEVEL=1

For those who are in the same situation (cannot update SQLServer) and are on Oracle Linux 8.2 (probably CentOS 8 too), just change MinProtocol to TLSv1.0 in the file: /etc/crypto-policies/back-ends/opensslcnf.config

[eddyprasetyo]

@lmtam
Yes. You could upgrade you SQL Server as @david-puglielli mentioned, or you could downgrade openssl minprotocol and CipherString.

    && sed -i 's,^\(CipherString[ ]*=\).*,\1'DEFAULT@SECLEVEL=1',g' /etc/ssl/openssl.cnf\
    && rm -rf /var/lib/apt/lists/*

the "sed" part very useful for me, on debian10 and in the situation of "Cannot update SQL Server"

Be careful and use TLSv1 instead of TLSv1.0

Cheers

Be careful and use TLSv1 instead of TLSv1.0

Why?
