• Operating System and version: Kali Linux 2021.1 fully updated & upgraded
• Python Version: ( python3 --version ) 3.9.2
• Python Environment: ( python3 -m pip freeze )

Current Behavior

runs well until this:
[-] 192.168.1.1:80 http exploits/routers/movistar/adsl_router_bhs_rta_path_traversal is not vulnerable
Exception in thread thread-5:

continues to run well
[-] 192.168.1.1:22 ssh exploits/generic/ssh_auth_keys is not vulnerable

it hangs at the end, never comes with the summary. Have to Ctrl C it to get back to command prompt of routersploit.

Expected Behavior

Run without interruptions and finish properly with vulnerability summary.
