If it helps to know, I didn't have that issue when I ran a Python program on Chrome earlier today.

Seems like only a few members have the issue, My best guess is the internet used (Starlink for me)

Also having this issue. Seems to be caused by a 403 error from a request made to the varnish cache. (Also using Starlink)

Also having the issue on all 3 of my computers with multiple browsers.  On Starlink as well, but used a different ISP and it worked fine.   

Okay, thanks for the feedback! 

It does seem to be an issue with Starlink connecting with KA. My guess is that Sstarlink has some sort of shield down to cause the problem.

I am in need of coding so I am in the process of creating my own code editor that is similar enough to be compatible with KA's 

I just switched to Starlink this week and I'm having the same issue! I'm glad I found people having the same issue. I'll run a Hotspot from my phone to comfirm to isolate the issue to Starlink and will come back with an update.

Ok, I just confirmed the issue isolation. I connected with my phone's Hotspot and the coding lesson worked as intended. It does have issues when I'm on the Starlink ISP. 
This needs to be looked into!

Thanks Ramon, always good to have more confirmation. I opened a support ticket a few days ago. I would think there must be a lot of people utilizing KA via Starlink.

According to a post in another thread about Starlink, 

... But in my experience using Firefox VPN works.

The reason why Starlink users are getting the issue is because the satellite you connect with is connecting to the nearest place on earth that it can so as it rotates your IP address is constantly changing which with the new KA anti-botting makes it look like a bot.

Me and my students are facing the same 403 issue even with using hotspot but we're not using starlink. However, it works on mobile using data

Do you know what Internet provider you are using?

With this type of thing KA either takes forever for a fix or they just ignore it because it isn't a majority.

I'm using Unify (Malaysia government cable)

Currently using university wifi and it doesnt work either

If a bunch of users used Report a Problem to report on this to KA staff, maybe they would pay attention.  (I've noticed many Support Community posts never get a response from KA staff, and I'm not sure whether they all even get read by KA staff.)

JaniceHolz I have a support ticket out (I think they may have closed it) But only got generic messages back from them. 

Yes. (the forwarded message piece was by me) Firefox VPN does work.

I also opened a support ticket.  They came back requesting more info which I provided.   Fingers crossed.  

I also opened a support ticket and they said they will look into it
