And this is from another page. Five minutes ago i got zero resources not loading. But i checked again and it now has 8 resources that did not load: https://snipboard.io/HD4y5Y.jpg . That is what i mean with the inconsistency.
Checking your site on GT Metrix, the only potential issue i see is the long time to first byte. This varies between 900ms and up 1.5s – this could cause the Other error when Googles servers are real busy. Might want to ask your host how you can improve the initial request time.
