Me too
Please lets know if you can fix it somehow. Have been waiting for hours to submit a solution but cannot
How did you solve this? I saw you submitted a solution on 25th September,but you asked about it 5 weeks ago.
After this post, I think after 10-20 minutes the site was under maintenance for a few hours and it was fixed then. Never expected it to happen again after 5 weeks.
Was facing the same issue. Could avoid it by using cloudflare WARP but it still occured a few times. Had to restart the browser before submitting.
I'm seeing the same behavior now
I just had this issue occur to me now, any solutions?
Not working at all. Facing this issue from last 20 mins.
Yes, I am also facing same issue.
same
Same problem here. Man, this is annoying...
i've tried deleting cache and cookies, i've logged out and in again, i've restarted my browser, and i've also rebooted my laptop. nothing has worked. so frustrating.
Currently facing the same issue.
I am not exactly seeing an "Unexpected error" but I am facing a very similar issue. When I do submit, I do not go to the submissions page as per the usual nor do I get anything there when checked manually. But when I attempt re-submitting, it says that I have submitted the exact same code before therefore I can not submit.
Any solution guys?
Me too, right when I was in the middle of a virtual contest :(
Dear MikeMirzayanov,Could you please clarify the cause of that problem?
after 5 weeks of this post this alien error is still happening...
problem fixed or what ??
Same, and the last week i have to verify that I'm human a lot of times
I have the same problem
I have the same problem (fixed) Have is main verb not a auxiliary verb here LOL :)
Have is main verb, not **an** auxiliary verb here LOL ;)(fixed) Auxiliary starts with a vowel sound, not a consonant! Hope this was just a rage-bait. (¬‿¬) (╯°□°）╯︵ ┻━┻ (✿◠‿◠)Thanks for correcting me
can't even submit a single problem aghhh
my last submission (40 minutes ago) is still in queue. Are others facing the same issue? If yes, GET WELL SOON CODEFORCES
No submissions since 15 mins ago! Seems that everyone got stuck.
I guess so..
yes it shows unexpected error occured
Been stuck with this issue since last night, tried switching browsers, devices, even using VPN, nothing seems to be working
Me too. But only on Google Chrome. No problem with Microsoft Edge.
I just tried with MS Edge, but the same problem occur.

Facing this issue currently, don't know how to resolve this
Yes , facing same issue .
How to solve this issue? I'm facing this problem. (Too frustrating)
I am also facing this same issue , this is literally frustrating
Same issue, I think Everyone is Stuck, Get well soon CF
Solved 4 problems and want to submit so badly...Why there is no update on it yet if many people are facing this problem?
The same problem happened to me now I have been trying to submit for more than 30 minutes
Just save your answer and do something else. Come back after 3-4 hours.
Meanwhile me seating infront of the submit screen from 2 hours :/
I've faced this problem today, what can I do ?
Any update? Waiting for a long time!
maybe the error in their server nor our system
I have been facing the same problem for 12 hours.
I am also facing this issue since yesterday... :(
I spent three hours thinking it was my internet problem, but then I realized many other programmers were facing the same issue. So, I understood it wasn’t my network problem—it was something else.
Facing the same issue too
the issue still persists, been waiting since (01-10-25, 21:30 IST):(
So we're not alone haha
What to do, how to fix.. It has happened to me also guyz
Same issue
Cloudfare WARP is enabling us to submit. You can use that, however, solutions remain in the queue idk why
:(
I got the same problem with the code submission, but the file submission was correct
I was facing this since yesterday. Tried restarting browser didn't work. Then switched to Chrome (was using Edge), worked for me. Hope this helps. But the submission is in queue, I hope it runs.
Same problem. I could submit a solution using the upload file section and then submit which is beside each problem statement but the regular "SUBMIT" section doesnt work. It shows unexpected error. The submitted file I submitted shows on queued. its been like this for an hour.
MikeMirzayanov can you please look into this issue?
How to solve the issue I am also facing this issue from morning onwards ??
I also tried submitting a solution from our national OI contest, but it showed an 'Unexpected error.' Then, about 4 hours ago, I submitted a solution to a problem from a recent Div-3 round, and it’s still stuck 'In queue'.
Same to me when I was doing my virtual participation
