My Docker container has no access to some websites(TLS Handshake) how can I troubleshoot this?

I have a server on which I want to deploy a container that needs access to the internet, but right now this only works for some urls and not for others.

In a container (behaviour is the same for all tested images but I am using docker run -it jonabelle/docker-network-tools) I am able to curlhttps://google.com and https://youtube.com while I'm getting timeouts for https://gitlab.com, https://wikipedia.com, and https://github.com.From the host I am able to curl all the urls successfully, it's just in the containers that I get timeouts.

In the container:

• nslookup works for the urls that are getting timeouts, so it's not a DNS issue.
• traceroute -I github.com also eventually arives at the ip that I got with host github.com.
• telnet github.com 443 and telnet github.com 80 connect successfully.
• but still curl https://github.com hangs indefinitely

The output of curl -v https://github.com hangs during TLS:

* Host github.com:443 was resolved.* IPv6: (none)* IPv4: 140.82.121.3*   Trying 140.82.121.3:443...* Connected to github.com (140.82.121.3) port 443* ALPN: curl offers h2,http/1.1* TLSv1.3 (OUT), TLS handshake, Client hello (1):*  CAfile: /etc/ssl/certs/ca-certificates.crt*  CApath: /etc/ssl/certs

I have replicated the same steps on my laptop, where it works, and compared the networking config with docker inspect $CONTAINER and docker inspect bridge(which is the network both containers are in) where, except for the network and container ids, everything it the same.

I am at my wits end here, connecting to github works on the server and in a container with the same network configuration on my laptop, but when running a container on the server, TLS times out.What I find especially weird, is that some urls work perfectly fine.How do I go about troubleshooting this?

For completion sake here is the network config on the server(except for the IDs they are the same on my laptop)docker network inspect bridge:

and docker inspect <container-name>
