How to open a network drive on MacOS?
Try to ping the website as an example
 ping engweb.eng.company.com, 
and get the IP of it. 

Then from "Connect to Server", put the network path as IP/bugs/files , and try to connect it as smb://IP/bugs/files . 

It could be an FTP network path so, worth to try ftp://IP/bugs/files, also you can try with cifs://IP.bugs/files if the above-mentioned option didn't work.
