Openvas 503 Service is down

When you install openvas first time it generate a certicate but this cetificate due after a year or as you specified on the generated scrypt. 

If after an upgrade o some time your server start generating this error and your not able to run the scan; this is due of certificate expired. So how you generate a new certificate and fix the server:

1. First generate the new certificate with the openvas script:

#openvas-mkcert -f 

the -f will remove the previous certificate install.



2. Install the certiciation on the client:

#openvas-mkcert-client -n om -i

3. Rebuild the database to see everything is working.

#openvasmd  --progress  --rebuild -v

4.  Restart the demons or reboot the server.
