Cant Access to OpenVPN server affter energy supply cut



  • 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
