Failure to Install Agent on Ubuntu 20.04

Remote Support and Access
1

Trying to install the remote support or even access agent on Ubuntu 20.04. Have both CLI and GUI access currently. When I download the executable from SH server and run it, I see my custom logo appear for a split second, then it dies. When I try and install via CLI I get the following dump of info (only pasting the last bit - my server name and IP address redacted for privacy)

Now, this appears to be a SSL issue. However, I’m confused as my site does have a valid cert, and everything seems peachy with all my Windows and IOS remote agents. It’s only when I’m trying to do this through Ubuntu it barks at me.

Out of desperation, I’ve tried to install lightpd to no avail. I’d be grateful for any direction here. Many thanks!

Hrm, after poking around a bit more, I decided to try and download via http instead of https, and ran it that way. It installed without issues and it appears my problem is resolved.

Still curious as to why it doesn’t work over HTTPS, but alas I am in the clear.

Leaving this as to maybe help someone else if they’re searching around.

I dont know for sure, but seems like wrong ssl/tls version being used.
Maybe your server is using an older version that was removed from your version of ubuntu?

Check what version tls your using on ubuntu?

Test and see if you can connect using wget or curl. you can specify diffrent tls versions in curl to test with too.

curl --tlsv1.2 https://mywebsite:443
