GIT pull suddenly hang

Question

I have no idea why lately my git pull started to hang

I've tried this already

git fsck && git gc --prune=now

Update

Network Firewall

This is what I set in my Network Firewall at Digital Ocean

I cant get to internet, and ping google

I can't ping or ssh from bitbucket

I even tried to disabled the firewall completely on the networking level, and inside the server level.I still seem the same result

What else do I check ?

Close any programs you have open that uses this repository (VS Studio for example). also, you can do `GIT_TRACE=true git pull` to find out where it hangs. — fredrik, Mar 21 '20 at 18:02
You can check this for a few things to check: https://stackoverflow.com/questions/44031150/why-does-git-pull-hang — fredrik, Mar 21 '20 at 18:03
If you're using SSH, run `GIT_SSH_COMMAND="ssh -vvv" GIT_TRACE=1 git pull` , and if you're using HTTPS, run `GIT_TRACE=1 GIT_CURL_VERBOSE=1 git pull`, and include the output as a text block in your question. — bk2204, Mar 21 '20 at 18:04
Check firewall rules, resolver settings (if you are using DHCP the resolver can be broken by the server), etc. I bet it waits for DNS timeout (leave it for few minutes to check). — 0andriy, Mar 21 '20 at 22:26
Just as a general rule, when something hangs, see if you can simplify it. Since `git pull` runs `git fetch` followed by `git merge` (or some other second Git command), see if `git fetch` hangs. If so, find out whether you're fetching over SSH or HTTP or HTTPS transport, and try `ssh` or `curl` or whatever command you have that implements *just* that protocol to see if *that* hangs. If so, check whether name resolution works and whether *any* network operations hang. If so, keep digging there, etc. — torek, Mar 22 '20 at 00:11
@0andriy, Thanks for the hint, I did tried everything I can on the firewall. I even tried to disabled on the Digital Occean, and in the server completely, that still happening. — code-8, Mar 25 '20 at 14:05
Check that SSH server accepted your kernel. It was a recent update to OpenSSH server to reject some keys. — 0andriy, Mar 25 '20 at 16:21
Incredible: I did mentioned explicitely (and in my answer) the /etc/ssh/ssh_config file in [our discussion](https://chat.stackoverflow.com/rooms/210339/discussion-between-vonc-and-cyber8200). So much timed passed for so little. — VonC, Mar 29 '20 at 16:57

In addition of traces, and protocols (SSH in your case), check the status of the remote hosting server you are pulling from.

For instance, GitHub had an incident yesterday, which can explain some delay in clone/pull request.

This DigitalOcean thread mentions:

I had to add outbound rule for SSH and DNS UDP

As mention in our discussion, the issue was /etc/ssh/ssh_config

Do you know why I kept trying to connect to BitBucket at port 8200 instead of 22 ? Where is the settings for that ?

That was the first line: Port 8080 to change to 22

@cyber8200 As commented, what is the output of `GIT_TRACE=1 GIT_CURL_VERBOSE=1 git pull` (if your remote URL is an HTTPS one) – VonC Mar 25 '20 at 14:29
I added *Update 4*, please have a look. It has the result you're looking for. – code-8 Mar 25 '20 at 16:09
@cyber8200 So... that is an SSH URL then: `GIT_SSH_COMMAND="ssh -vvv" GIT_TRACE=1 git pull` – VonC Mar 25 '20 at 16:13

@cyber8200 Possibly in `/etc/ssh/ssh_config` or in `~git/.ssh/config` – VonC Mar 25 '20 at 17:30
I see port `8200` in my `/etc/ssh/ssh_config`, but nothing in `.git/config` – code-8 Mar 25 '20 at 18:17

As i see your outgoing ssh connection is going throught port 8200 instead of 22.
So please make sure to check the line start with Port 22 in file /etc/ssh/ssh_config , you should comment it out if it enabled.

Why are you trying to connect to bitbucket.org via port 8200?

Shouldn't you be using port 22?

Also bitbucket.org has disabled ping on their end, so to test your connectivity to the site you an do:

curl -skLi bitbucket.org

I update my ssh port to 8200. I didn’t used default 22. – code-8 Mar 28 '20 at 12:45

The ssh port on Your machine is 8200, which is fine, but I see you are trying to connect to `debug2: resolving "bitbucket.org" port 8200 ` which should be `debug2: resolving "bitbucket.org" port 22` – Ron Mar 28 '20 at 16:30
