Can't load page while dev-console is open

Question

Today i encountered a problem using chrome. Everything worked fine yesterday, no new plugins or anything installed, chrome is still the same version.

Whenever I have the dev-tools open and try to reload the page, chrome tells me, it can't get a connection. The console also drops this warning:

/deep/ combinator is deprecated. See https://www.chromestatus.com/features/6750456638341120 for more details.

I already searched for this, but couldn't find any help. Hope you can help me with this problem. Never had any problems like this before.

From the description, it appears that you have Network throttling setted up as Offline in DevTools. See in the Network Panel, by default it should be on No throttling:
