QUIC.cloud CDN Error 520 and 524

    Hi,

    I am getting errors on all my QUIC.cloud websites. There are four different websites and none of them is working with QUIC.cloud CDN turned ON.

    QUIC.Cloud FAQs page (https://quic.cloud/faq/) suggests that I should contact my webshost in case of 520 error to whitelist all the IPs. I contacted them and they told me that none of the IPs are blacklisted.

    The FAQ page also suggests that I should contact LiteSpeed in case of 524 errors.

    Could someone please help me figure out how to resolve this issue?

    Thanks.

    Hi,

    could you please provide the report number ?

    you can get it in toolbox -> report , click “send to LiteSpeed”

    in Note, you can also provide the domain that gives you 524

    Hi @qtwrk

    I have sent two reports from two domains reporting error 520 and 524.

    The Report numbers are: VBGINODB for error 520 and CVQYBSXX for error 524.

    I have also sent the domain name in the notes for both reports. ??

    Hi @qtwrk

    The websites seem alright now. I was able to hit private QC cache for the webpage I visited.

    If possible could you please explain, what caused this issue?

    Thanks. ??

    Hi @qtwrk,

    The 520 error has again started appearing on the website. Would it be possible for you to take a quick look and see what’s wrong?

    I will try to keep the website in this state for a few hours. I hope you get this message before that. ??

    Thanks.

    Hi,

    it still loads fine on me.

    Could you please indicate which node you’ve connected to ?

    you can get it in HTTP response header, looking for “x-qc-pop”

    @qtwrk Yes, it started loading without any issues after I posted the comment here.

    It seems to be appearing “randomly”. Here are all my response headers:

    I will post my response headers again if the error pops-up in the future. ??

    Thanks.

    The problem lasted for 2-3 hours this time and pages started loading normally about half an hour after I posted my comment. I did not make any changes on my end this time.

    Before that, when I originally started posting in this thread, it persisted for about 10-12 hours.

    Hi,

    Well, For QC issue as it may requires more quicker/faster response , it is better if you can join our Slack community , where you can receive more real-time information and communication.
