Why do some web browsers show that it has been loaded, but it is still a blank page? Is it blocked? But it got better after many refreshes.

I try to crawl some of the data with the python crawler, but sometimes the browser shows that it has been loaded, but the display is still blank.
then I need to refresh multiple times to recover. What"s even weirder is that you can"t refresh it many times with Chrome. If you change it to Firefox, you"ll be fine immediately, or if Firefox doesn"t work, Chrome will be fine.

I try to refresh automatically with selenium. I can"t refresh it many times, not even changing browsers. The page can only be refreshed manually. How did this happen?

add: in this case, if the status code returned with requests is 200, it is normal, but the text is empty. Which means nothing.

Don't bother you, I found the cause of the problem. I used the agent to look at the page and visit it. I think ip is blocked.

Previous: Github pages is bound to the domain name, so I can't log on my blog directly.

Next: When I visit this javaWeb project in my browser, I always remind me of the wrong path. I can't see what's wrong for a long time. Please give me some advice.
