Disabling TLS 1.0/1.1 renders the APM Insight .NET agent completely useless.
We had to disable TLS 1.0/1.1 last week to adhere to our payment gateway provider's guidelines. It should have already been disabled, but the app developer forgot to mention it.
Once TLS 1.0/1.1 are disabled, the APM Insight .NET agent no longer functions. The services starts and runs, but is unable to establish a connection - "(Could not create SSL/TLS secure channel).
I worked with Site4x7 support this morning and there is no fix until they recompile with the latest .Net version with TLS 1.2 support.
I haven't found anything in the documentation that states TLS 1.0/1.1 are required, but this is a setback for us. We can't enable TLS 1.0/1.1 and we now have limited monitoring/insight into the .Net apps.
Hoping they can get a new version released soon.
