It's for a day that I can't login through SSH to my servers. Using both Putty and MobaXterm. MobaXterm ends with:
debug1: sending SSH2_MSG_KEX_ECDH_INIT
debug1: expecting SSH2_MSG_KEX_ECDH_REPLY
Read from socket failed: Software caused connection abort
I searched about the issue and found that it could be a MTU specific problem, but how is it possible to fail suddenly to login to different servers?
This is one of my debug enabled -v
connecting sessions:
OpenSSH_6.7p1, OpenSSL 1.0.1g 7 Apr 2014
debug1: Reading configuration data /etc/ssh_config
debug1: Connecting to XXX.XXX.XXX.XXX [XXX.XXX.XXX.XXX] port 22.
debug1: Connection established.

debug1: sending SSH2_MSG_KEX_ECDH_INIT
debug1: expecting SSH2_MSG_KEX_ECDH_REPLY
It hangs at this line and after seconds ends with:
Read from socket failed: Software caused connection abort
I really appreciate any help.
