Same here. Just this morning. Internet is fine. Just adding an extra report.

Alright, looks like it’s resolved for now. We’re still looking into the long-term solution for this one. Thanks for the reporting everyone (and robots that keep us up-to-date no matter the time of day).

Figured this information might help a developer figure it out.

Here’s what I’m seeing in the network tab of my browser:

Reviews 2020-06-15 20-07-40
Reviews 2020-06-15 20-07-401293×505 108 KB

This seems to be triggered by this $.ajax call in the application.js source:

$.ajax({ url: "/json/progress", type: "PUT", data: o, dataType: "json" })
  .fail(function (t, i, r) {
      var a;
      return (
          (a = $.jStorage.get("submitFailedQueue") || []).push({ id: u, mi: n.mi, ri: n.ri }),
          $.jStorage.set("submitFailedQueue", a, { ttl: 36e5 }),
          WaniKani.exceptions.submitErrorReport("reviews", "processCompleted", r, t, i, params, e.errorDetails())
      );
  })
  .done(function () {
      return (e.lastItemProcessed = !0);
  })

I believe the fail function is being called here because the request is failing (it’s a 500 in the network tab).

In my JS console, I see this:

This seems to be a side-effect of the error; the params variable is indeed not defined – I suspect in this minified code it’s the o variable, but I could be wrong.

The JS file that I am served from the CDN is https://cdn.wanikani.com/assets/v03/review/application-5d0ab0ab2d1f843524a299e74670ab89c9b8ea92b73a3284cbc7c1c841e2e596.js. A http HEAD on this URL shows these dates:

Date: Tue, 02 Jun 2020 21:55:51 GMT
Last-Modified: Tue, 02 Jun 2020 21:51:01 GMT

FWIW, re-submitting the JSON progress network request (Right click in network tab → “Resend”) seems to work fine.

Possibly an intermittent server issue? I don’t know. I’ll leave it to the code legends :slight_smile:

I`ve been getting the same problem. The funny thing is - after the no connection pop-up, I can continue to input answers and Wanikani will accept them, but it’s a bit inconvenient, so I just click refresh button as the pop-up suggests. :smile:

34

Same here, also seen “Something went wrong” when trying to access WaniKani, but refreshing the page solved the issue

35

Same here - getting the refresh prompt every few words for the past hour or so. Refreshed during a lesson quiz and it changed some of the lesson Kanji :sweat:

36

I had it yesterday too, got better (the fix =) ) but now it is back again.
Sneaky little bugger this one!

I might lose connection to WK, but I will never lose connection to my inner crabigator.

Great attitude! :+1:

I just had a bout of this issue. It was like one time-out per 3-4 items. That’s a lot. Previous time-outs I’ve had have been a rare occurrence, so this is clearly something new. I do hope a fix is around the corner!

Wanikani reached out on Twitter to me last night claiming that the issues are fixed.

But sadly I am still seeing issues tonight.
