Cant Access to OpenVPN server affter energy supply cut

Delyryus

Hi, First sorry for my English, im from Argentina... Im running OpenVPN in Pfsense 2.4.3-RELEASE-p1, We have a power loss and the server stop working... the Server was working fine before the cut.

When the power comes up i have the error

"Shared object "libdl.so.1" not found, required by "openvpn"...

I try the solution : "ln -sf /lib/libc.so.7 /usr/lib/libdl.so.1"....

Ok the server runs agains, but i cant connect to it... the client never see the Server..

In OpenVPN logs it say

EDIT: I try to copy libdl.so and libdl.so.1 from freebsd bot ISO but same thing.. no work for me :(
The portforwarding from router to Pfsense works fine, i can access to Config page from public IP.

Thx!!! and sorry for my English again!!!

XOXO Marcos =)

Sounds like your filesystem got corrupted due to the power cut.
Make a Backup and do a quick reinstall with the Recover Config Option: https://www.netgate.com/docs/pfsense/backup/automatically-restore-during-install.html
