It occurred to me when selenium automated code was clicking on an element of my work dev website and the connection between Selenium and the Web driver controlling the browser was lost, ultimately leading to the failing of all remaining tests after it.

Upon looking at the URL, I found that '//' was added to it for some unknown reason. Modifying it to '/' resolved my issue.

My work URL (with error): https://workdevurl.com.sa:81//CaseCustom.aspx?id=1359&formId=4206&ccf=96352

My work URL (after rectifying it): https://workdevurl.com.sa:81/CaseCustom.aspx?id=1359&formId=4206&ccf=96352
