Thank you for your contribution, it is an awesome tool !!!
The program throws an exception when I try to run the following command.

Bash:

./wcvs -gp ./log -gr -gc -uac -r 2 -rl 3 -red templates/recdomains_list -st parameter -u https://6o4xu.vk.com

Error Message:

GetWebsite: Get "https://6o4xu.vk.com": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

Thank you for the information! I will take a look at this next week. Sorry for this uncaught error

The cause for the runtime error was found and fixed: see commit 528397d4d254d4c01eb9a0ff021fe79c5c79d5f2

If you want to fetch the repository yourself or use the docker image, you can already use the improved version. Otherwise you will need to wait approx. 1-2 weeks until a new release is made, as I'm working also on other improvements.

Thank you for pointing this error out! If there is any other problem, question or something else, feel free to respond here or to create a new issue.

This issue will be closed if the new release was published as others might also experience this error.
