github.io web link is broken
The official web link for this project is https://python-visualization.github.io/folium/
yet attempting to visit it yields:
This site can’t provide a secure connectionpython-visualization.github.io sent an invalid response.
[Try running Windows Network Diagnostics](javascript:diagnoseErrors()).
ERR_SSL_PROTOCOL_ERROR
I can access it no problem. Also, it is under GitHub' s umbrella a d it is HTTPS. Can you access other GH pages? If not, It may be a problem with your browser or local config.
I am seeing the same issue preventing the viewing of the docs. I can view other GH pages fine, e.g. yelp
Chrome:
Firefox:
Not sure what's going on here. We don't use a custom domain, so it's up to Github to make sure this works.
I ran this tool (https://docs.github.com/en/pages/getting-started-with-github-pages/securing-your-github-pages-site-with-https) even though it's meant for custom domains and it said:
I found these general errors in the configuration for https://python-visualization.github.io/folium/: Your site's DNS setings are using a custom subdomain, python-visualization.github.io, that's set up as an A record. We recomend you change this to a CNAME record pointing at [YOUR USERNAME].github.io.
🤷♂️ not sure what to do with this since we don't manage the DNS records for github.io.
One thing we could try is to enforce HTTPS, that is not enabled yet: https://docs.github.com/en/pages/getting-started-with-github-pages/securing-your-github-pages-site-with-https#enforcing-https-for-your-github-pages-site
If that doesn't work we should contact Github.
Probably related earlier issue: https://github.com/python-visualization/folium/issues/1771
I've enabled enforcing HTTPS. @metaperl, @SamKnightGit, could you maybe let us know if that changes things for you?
Thanks for looking into this. I can confirm I am still unable to access the pages on both chrome and firefox.
This SSL checker doesn't report any issues: https://www.sslshopper.com/ssl-checker.html#hostname=https://python-visualization.github.io/folium/

Can you try a non-root doc? Like folium is. For example: https://ioos.github.io/erddapy/
Just trying to narrow down the possibilities here.
Ah, sorry for the wild goose chase. I can load the link fine using cellular data so it must be an issue with my ISP -- probably some safety feature overreaching. FYI I'm using Virgin Media (had to turn off their WebSafe feature) for anybody else that may encounter this issue.
Thanks for reporting back, glad it works now!
@metaperl do you still experience problems?

It may also be an issue with my ISP. But I do get the error for it even now:
It may also be an issue with my ISP.
I switched to my phone internet (AT&T) and still have the problem. Comcast business is what the above screenshot came from. Neither works for me... let me try a different browser.
let me try a different browser.
Normally I use Vivaldi but I just tried Firefox and it failed also.
I posted in the Github community discussion, curious to see if we get any response there! https://github.com/orgs/community/discussions/65916
I was running into this problem last week, however when I tried this today, the docs work!
Same problem here from Switzerland, from an otherwise great ISP. Something fishy is going on here...
I have no idea what could be the issue.
- could it be because we don't have a favicon? I can't imagine why that would break everything.
- I changed the redirect in index.html to a relative url. No idea if that actually helps.
I thought it was fixed for a while, but the problem is unfortunately back. The problem might be slightly different:
An error occurred during a connection to python-visualization.github.io. PR_END_OF_FILE_ERROR
Error code: PR_END_OF_FILE_ERROR
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
Potential hint: the http version gives me the following page:
This suggests that my ISP may be involved. I will try to report it.
So I reached out to my ISP, they double-checked the "security issue", and removed the warning. The problem is now gone for both https and http. I assume there was at some point an issue with the page that caused certain ISPs to blacklist it, and the problem is now gone. So, everyone affected should probably reach out to their ISP.
Interesting! Thanks for letting that know @joelthelion. I guess that means if that's true there's nothing to change to the current setup, since the damage was done in the past.
