Skeleton Soldier Couldn't Protect the Dungeon https://mangadex.org/chapter/534089/1

I can't seem to be able to download the chapters of this manga, other mangas download fine.

I started the download this morning and as you can see it downloaded a couple of chapters without a problem then locked itself.

    I just tried and it worked for me:

    From what I read in the log file it seems that the errors always occur about 60 seconds after the download starts, as if it reached the timeout. Maybe it was just a temporary problem of their server, can you try again to see if it works for you now too?

    P.s .: if it does not work for you, please activate the new option (in the Edit menu) to save the JVM log messages to file and upload the jvm_log.txt file (the program should create it in the same folder where is its executable), that log is definitely more useful to identify what caused the errors, thank you

    🤔🤔🤔 that.... might be the case... i've had at least one chapter stop mid-download. But most chapters either download completely fine or never download, and it's always the same series.

    for now i've had: https://mangadex.org/title/32834/oversimplified-scp https://mangadex.org/title/31975/asebi-and-adventurers-of-sky-world https://mangadex.org/title/28778/skeleton-soldier-couldn-t-protect-the-dungeon other mangas download perfectly fine.

    I'm now updating and will retry downloading these 3 above by using the advanced log as you asked.

    tried to download several chapters and then aborted each time. This is what came out after i closed the program. Last chapter was only partially downloaded.

    Thank you, exactly as I imagined they are all timeout errors ("ConnectionPoolTimeoutException: Timeout waiting for connection from pool"), what values do you have for the connection and read timeouts in program's settings? Do you have this issue only with MangaDex? From other websites the program can download without issues?

  5. Simone Spinozzi

    i can download even from mangadex without issues... it does so only on specific comics and let me make screenshots of the settings.

    Thank you, I'll try to analyze again the download function to see if I could optimize it to reduce the timeout risk of if it has any connection leak issue

    also, it should probably be of note that i have zero problems downloading the comics via the usual f12 trick it just takes a lot of time, and yeah every single page loads without problems.... but then again i live in the italian country side sooooooo..... yeah 19€/month buy me 4 megabits. However no page ever needs 60 seconds to load. I don't know how sensible is your program to lost packets or something.

    I found a little bug in the download function that could indeed bring to a connection leak, but I don't know if it is enough to cause similar timeouts. However, please test it (I just released the v8.5 with the quick fix) and let me know if the errors still occur, thx

    Does it give you 503 http error? It seems that MangaDex enabled the cloudflare protection so it seems that they were really issues related to their server xD

  10. Red Squirrel repo owner

    Yeah, it's cloudflare indeed ("HTTP error fetching URL. Status=503,"). Ok I have enabled the bypassing function for cloudflare to all the websites now, please try again (it should work now even if it still say 8.5)
