Can no longer update using GIT

@cjp82placer Next, on your fog server try this one:
curl https://www.google.com/

What’s your machine’s timestamp compared to an atomic clock?

Atomic clock can be found here: https://www.time.gov/

Of course your timezone will adjust slightly, but the main point is you cannot be more or less than 5 minutes of the atomic clocks (typically) as that will cause the SSL cert to be invalidated (hence the ssl error you’re seeing.) Of course there could be many other reasons to what’s causing this, but I would recommend checking the time first as its the simplest course of action.

@wayne-workman No error with this command.

cjp82placer

@tom-elliott I am within seconds of the Atomic clock, but the time was off at one point in my troubleshooting.

Wayne Workman

@cjp82placer Ok since the time has changed - rerun those commands to see if the issue is resolved or not. Also, add a ping command which will test DNS resolution:

# Just check if the curl succeeds or not.
curl https://github.com/ > /dev/null 2>&1;echo $?
# Just check if the curl succeeds or not.
curl https://www.google.com/ > /dev/null 2>&1;echo $?
# test dns resolution of google.
ping -c 4 google.com
# test dns resolution of github
ping -c 4 github.com
# Directly ping one of github's IPs
ping -c 4 192.30.253.113

@wayne-workman Here are the results; the pings were all successful but the curl command is still failing as is the git pull command.

@cjp82placer Do you have a web filter of any kind? You should check it to see if it’s blocking github.

Sebastian Roth

@cjp82placer Possibly some kind of reverse SSL proxy within your network that is intercepting and maybe filtering all HTTPS connections?

Quazz

What OS and version are you running?

What does curl https://github.com --cipher rsa_aes_128_sha get you.

Curl error 35 is:

"Cannot communicate securely with peer: no common encryption algorithm(s)."

The local and remote systems share no cipher suites in common. This can be due to a misconfiguration at either end. It can be due to a server being misconfigured to use a non-RSA certificate with the RSA key exchange algorithm.

Also try curl https://github.com -v it should give us more info

@quazz Update… Updating cURL was the answer.
