ping but no connection with Putty

[kowokowo]

The last 2 weeks the Pi with Owncloud installed on it has a strange problem.

After a random time, I can not access to the Pi with Putty from a client computer.
Ping still works, but connecting to the owncloud via Browser ( http://192.168.1.25/owncloud) fails.
The only option that works is, rebooting the Pi (hard reboot -> removing power adapter!!)

The Pi worked fine for nearly a year.

Who can help me

Have a look in the /var/log/auth.log file. You might find some hint of why your ssh connection failed.

Code: Select all

grep sshd /var/log/auth.log
