Hello there, @alan9990 said in Help to diagnose intermittent page load error: I find that I'll fire up Vivaldi only to wait while the sight of a completely blank tab The lack of UI happens during the Vivaldi start-up or while with loading a website? I am asking you just in case. @alan9990 said in Help to diagnose intermittent page load error: Either the page then decides to load, or we get the variety of "destination unreachable" or other related type of message. Ever tried to ping the page? We know pinging is not a prerequisite lo load a page. Any http error number? @alan9990 said in Help to diagnose intermittent page load error: . It's quite common for me to watch the page load in the url window, only to see it stall on 35/36 Frequently I got it - "non stop loading" - F5 sometimes leads you to the same 34/35. I don't know how to fix. @alan9990 said in Help to diagnose intermittent page load error: is there a command line tool or a script that I can use that will expose the chain of events from clicking in the search field, or clicking on a search result or bookmark to open a tab. The Dev Tool (Ctrl+Shift+I) can do that - Network tab Here is my suggestion: open the terminal, and issue the following command: $ /usr/bin/vivaldi-snapshot --user-data-dir="/tmp/VIV-TST" & It's a temp install, won't messed up your Vivaldi. In case you are not able to repro the network problem, then the issue lies on your profile folder. Edited: Typo
