[AMBER-Developers] problem connecting to amber git

Hi All,

We are having some strange errors when connecting to amber git. Just
wonder anybody has had the same issue or has any clue to solve this?
Basically, doing 'git pull' on our server will give the following error:

ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

The 'git clone' and 'git submodule update --init' commends were
successful a while ago, but they don't work any more either.
Troubleshooting with 'ssh -vvvT gitosis.git.ambermd.org -i ~/.ssh/amber'
gives the following message:

OpenSSH_7.4p1, OpenSSL 1.0.2k-fipsĀ  26 Jan 2017

The weird thing is my workstation has no problem using same ssh
key-pair. So it seems like our serve was blacklisted somehow by amber
git host. I tried some possible solutions but still no luck. From this
post, http://edoceo.com/notabene/ssh-exchange-identification, there is a
possibility that the problem is with the host side. So could anybody
look into this please? Thanks a lot!

Best,

Ruxi
