Since yesterday I can't edit, can't view preview of any page and can't patrol edits in all Wikimedia projects. I simply get ERR_CONNECTION_RESET in Chrome and get nothing in Mozilla (the request is stopped, the page remains in the same state). However, I can ping this sites, I can rename pages,I can revert edits from history page and I can edit Wikidata items.
This problem is relevant for any browser on my PC and even for my tablet on Android (all in my home network), it does not depend on logging in/out.
I'm the only user who has this issue now I know. It has been discussed in Russian Wikipedia whiout any resolve (best advice was to write here). I took part in discussion via TeamViewer from my PC at work. Even the Opera VPN did not help me, although I installed it today for this.
I don't know how to reproduce it, my internet provider told me that nothing had changed on his part past two days. But I noticed that MediaWiki 1.32/wmf.13 had been introduced yeasterday.
