HTTP error 35 - SSL/TLS handshake issue

[mathiasvandel]

Hi,

I am getting HTTP error 35, which seems to be a curl SSL/TLS handshake issue.

Is there any way this can be fixed?
It is not an option to turn of HTTPS.

Best,

Hi Mathias,

Can you share (either here or via DM) what third-party HTTPS service you’re trying to reach and roughly how many imp agents seem to be affected?

When you get such an error, do you have a backoff strategy for retries?

Thanks,
Phil

It looks like the particular server only accepts TLS1.3 while agents support up to TLS1.2.
