Is aktualizr using TLS 1.3

[Moeed148a]

I have update the ngnix version in the docker compose file in the ota-community-edition
https://github.com/uptane/ota-community-edition/blob/v2/ota-ce.yaml

Now when i try to connect the aktualizr to the ota-community-edition server. It shows the following error. Kindly help me.

TCP_NODELAY set​

• Connected to ota.ce (127.0.0.1) port 30443 (OTAC-SYS-1 Add usage information when --help is passed #1)​

• ALPN, offering http/1.1​

• successfully set certificate verify locations:​

• CAfile: /tmp/aktualizr-5985-3051-b8cd-db04/33f6-35cf-tls-ca​

CApath: /etc/ssl/certs​

• Closing connection 1​

• Hostname ota.ce was found in DNS cache

Because the nginix server is running on the TLS 1.3. The link for ngnix docker file is below

I don't believe aktualizr specifies a TLS version, so this depends on other dependencies. However, see also uptane/aktualizr#83.

FWIW I strongly recommend using the Uptane version of this repo, as it includes many fixes not present in this version.
