[Mangahere] random invalid URL

Any chapter : unable to preview

Behavior is incosistent, sometimes it works but when it fails it's persistent for a good while

DM5.ts:75 Uncaught (in promise) TypeError: Failed to construct 'URL': Invalid URL
at DM5.ts:75:54
at MangaHere_default.FetchPagesSinglePageScript (DM5.ts:75:19)
at async Chapter.Update (MediaPlugin.ts:96:34)

At the same time works fine in hakuneko

I'm unable to see http traffic for mangahere in network console (I was able in haku)

Edit: trying to browse mangahere from the internal browser is suddenly slow browsing the website. Works fine in the OS browser
Still investigating

Edit2: website is now also slow within the OS browser. Possibly related to an IP throttling mechanism

I got errors on mangahere in mihon too and people complained on discord. In Browser pages load then randomly dont load, i dont think is from us.

[Sheepux]

yeah that's the conclusion i'm reaching, their website doesn't seem stable

[Sheepux]

However, the message is "un-understandable". Invalid URL doesn't tell much

[MikeZeDev]

You have no network activity shown because its an injected script and not a direct Fetch. Pages are eval(packed) in chapter , we have to do that.

And for the message, well, its default Javascript error returned from failed promise. Since executing JS is a blackbox its better to have the real JS error than an obscure "cant get pages bro". Its sad fro users tho 🤷 .

Perhaps it could be improved : "Cant get pages : <error>"

In browser and haru ive seen the infamous "Sorry" Cloudflare page from their CDN, its a CDN problem.
Remember it will also affect websites that hotlinks from mangahere like Mangatown

[Sheepux]

Morning attempt, website is working fine. Haruneko is stable.
Note for self :
haku is processing for 4s while the website itself loads in less than 1 seconds. An optimisation could be investigated.

[MikeZeDev]

Depends on what you mean by processing. We have to open a browser window , execute some JS, and stuff. If you add the necessary delays perhaps its not abnormal.

[Sheepux]

It was almost instant before. Something changed that might be delaying something (both in haku & haru)

[MikeZeDev]

You realize that something couldnt have changed in haku? related code shouldnt have changes for ages afaik.
I just tried, in kinda instant.

[Sheepux]

Not on my side. This is issue is for myself/investigation

[MikeZeDev]

In Haku i can see some slowness on FetchUI for some manga but we didnt change fetchui. Perhaps they added more crappy ads/scripts on the website idk. It could slow down Haru too..

[Sheepux]

therefore this PR but it didn't solve. That's why there is this thread: something changed on their side (i'm using a locally non refreshed git clone in haku), I still don't know what.

[MikeZeDev]

If you ever find a manga where we can reproduce that, tell me. I had one but i forgot to note its name.
