Website Scanner is stuck at 47%
Sometimes the Website Scanner may remain for a while at 42% or 47% but it’s not stuck. We recommend you to let the scanner open even if you see it stagnate.
Since the web server scanner can make a considerable number of requests to the target server, the whole scan could take up to several hours.
OpenVAS getting stuck at 95%
Network Scan OpenVAS can take up to several hours. We recommend you to let the scanner open even if you see it stagnate.
TCP / UDP port scan stopped at 50%
This step usually takes longer to complete, we recommend you don’t stop the scanner even if you see it stagnate.
