RStudio Cloud not loading at home

When I click the log-in button at rstudio.cloud while I'm connected to my home WiFi, the log-in page doesn't load. My internet is working for other websites. This issue was happening yesterday, too. I went into the University and was able to access the log-in page from there. I would like to be able to use RStudio Cloud at home. Does anyone know what might be causing this problem?

Here is a screenshot of the error message that appears after Safari stops trying to load the log-in page:

Update: It worked the moment I connected to the internet via an ethernet cable. I guess my WiFi connection isn't strong enough? RStudio Cloud used to work at home on my WiFi.
