I just visit https://direkt.bahn.guru/ with Firefox 94.0. Already disabled some add blockers and see no difference.

Ah there is a CORS error:

Hey 🙂 Thanks for reporting this, did you enter a station at the top right? If so: Which one?

rugk commented 2 years ago

No, I just visited the website… :upside_down_face:

rugk commented 2 years ago

Ahhh I need to enter sth. Very good, now I see what this website is about.

It's basically an isodistance map (yes I also needed to look for this term yet again – and I thouht there was also a wikipedia article for that as there were even hand-drawn maps of this kind before… uhm… "technology happened", but I am getting off-topic…) like https://commutetimemap.com/map.

rugk commented 2 years ago

Anyway, the CORS errors are likely still a kinda bad sign and should be fixed… :upside_down_face:

Site used to work for me but is now broken. A lot of CORS errors in the log and city search returns nothing. Firefox 100 and Edge 101 image

When searching for a city this is returned: GET https://v5.db.transport.rest/locations?query=berlin&poi=false&addresses=false net::ERR_CERT_AUTHORITY_INVALID bundle.js?v5:2

Feels like something on the DB end is broken

juliuste commented 2 years ago

Regarding CORS errors: This seems to be the result of adblockers like uBlock Origin blocking mapbox event requests (see also: this issue), the site should work fine nonetheless, and there is not much I as the site's maintainer can do about the errors appearing in the logs, afaik.

@ElectronicWar regarding the certificate error: I cannot reproduce this, v5.db.transport.rest has a valid cert as far as I can tell. Are you sure that everything is "normal" in your certificate setup (e.g. with your list of trusted CAs)?

ElectronicWar commented 2 years ago

I have re-tried at home and the error was caused by the office network. At home it works with ad-blockers disabled! Sorry for the false alarm.

juliuste commented 2 years ago

Alright, that's good to hear! 🙂 I think all issues reported here are resolved/clarified, so I'll close this for now, please re-open if I missed anything
