Issues with local analysis - web engine

I am currently having severe issues with the local analysis on lichess.

Whenever I reach a position that is not available via cloud analysis and try to analyse with the browser engine locally, "loading engine" is displayed, but it won't work.

Is anyone else experiencing something similar, or has an idea about the problem's origin ?

@on1000000squares what browser are you using? and is it up to date and try a different one?

The problem seems to be independent of the browser or device I am using.
Browsers I tried: Chrome, Firefox, Edge (on both phone and pc, while software is up to date)

@on1000000squares said in #1:

I'm having the same thing, when I'm doing puzzles and analyzing after, it's says "loading engine..." and keeps doing that for very much longer than I'm used to. I often have to go back and forth to get it to work and actually start the evaluation.

Android Firefox 134.0

Choosing Stockfish 11 seems to avoid the problem for me, but both SF16 and 17 are not working properly.

looks to be a bug on lichess end with the memory
SO hopefully they fix it soon

What I am noticing is, that if I choose SF16/17 and start the engine(or try to) there is no extra working memory(corresponding to what I choose in the engine settings) allocated to my browser, choosing SF11 this is happening.

I have the same problem.

Same problem here! I hope they fix it soon, it is a mayor bonus for Lichess to have this feature for free (if it works)

Same issue. It’s been happening for a couple of days. When will it be fixed?
