After loading Password Manager in Chrome I cannot load Service Desk

Both PW Manager and Service Desk work alongside each other in Internet Explorer and also work separately in both Chrome and IE. However if I open up PW Manager in Chrome and then attempt to open Service Desk in Chrome the page does not load and it returns an SSL Error saying that it cannot get a secure connection but works if Password Manager was never opened. To be able to open Service Desk again I have to close the tab Password Manager was open in and clear cookies and site/plugin data. I have tried using the PW Manager Chrome extension but that still does not work alongside Service Desk. Any ideas on what may help to sort this?

Thanks
