Hey @irenehardy – Thanks for those extra details.
It’s hard to know for sure what’s going on without seeing actual errors within the Browser console, but one thing I notice is that the gulpfile.js config is using https as opposed to regular http. My guess is that Browsersync is having issues connecting over HTTPS to the Local site.
I know that it’s possible to get Browsersync to work with an HTTPS backend, but I’ve always felt that it’s been finicky and more trouble than it’s worth. As a start, I would try making the site in Local be served over regular HTTP and then change the proxy value to use the regular HTTP protocol, like this:
http://example.local
Can you give that a try and let us know how it goes?
