allsky Website should only display "can't find" message if image.jpg is missing twice in a row.

Problem

If "image.jpg" isn't found, an Allsky Website will display the "The image at image.jpg is not found or is corrupted" message. This can legitimately happen in that very small window when the old file is removed and the new one renamed to "image.jpg".

Fix

Only display the message if at least 2 failures occur in a row.

Inserted the .js code as you requested...warning periodically pops up yet....

Maybe I need to increase the delay between images? Currently set at 20000...

P. S. Have not had the opportunity to run the grep request yet... Will do that later today.

Changed Debug Level to 3 as requested. Re-ran allsky-config check_post_data as requested - these are results:

n8yel@allsky:~ $ allsky-config check_post_data

*** Testing postData.sh...
    postData.sh succeeded:
        upload.sh: FTP '/home/n8yel/allsky/tmp/data.json' to dutchghe @ panel.freehosting.com 'public_html/allsky//data.json'

*** postData.sh ran 2 time(s) recently.

*** Checking for recent failures...
    No failures found.

Could not find any problems with postData.sh.

n8yel@allsky:~ $

The 2 forward slashes seem off to me

Question: On the WebUi, the 'Websites and Remote Server Settings' what is the proper syntax format for that?? I have mine set at this: public_html/allsky/

Edit #2 I think I solved the double forward slash result - re-running the check_post_data showed the following now:

n8yel@allsky:~ $ allsky-config check_post_data

*** Testing postData.sh...
    postData.sh succeeded:
        upload.sh: FTP '/home/n8yel/allsky/tmp/data.json' to dutchghe @ panel.freehosting.com 'public_html/allsky/data.json'

Thought maybe you might like/want to review this - I'd be curious to get your thoughts. Thanks.

What am I supposed to look for?

I see:

You fixed the "type" of several variables.
You appear to have changed something on March 20 around 3:18 pm because libpng warning: iCCP: known incorrect sRGB profile messages started appearing and uploads failed since /allsky doesn't exist.
Around 3:45 you fixed the /allsky problem.
Around 21:19 on the 20th you covered the camera or turned off the lights? Something happened to significantly darken the images.
Around 4 am on the 21st whatever happened in the prior item went away.
Around the same time you started having occasional network problems.

Also:

I suggest applying the fix at https://github.com/AllskyTeam/allsky/issues/4435.
Please run ls -ld /home/n8yel/allsky/config/modules. If it doesn't return this: drwxrwxr-x 2 pi www-data 4096 ... do the following: sudo chgrp www-data /home/n8yel/allsky/config/modules; chmod 775 /home/n8yel/allsky/config/modules
Run ls -l /home/n8yel/allsky/config/modules.

Comments on your earlier post:

You can ignore the double slashes. Linux treats "//" like "/". However, the next release will only have one slash.

Maybe I need to increase the delay between images? Currently set at 20000...

The delay you have on the Pi has nothing to do with the image.jpg" isn't found message. In your browser, please press F12 and in the right side of the screen, go to the "Console" tab. Next time you get the error message, attach a screenshot of the Console messages. After that happens, until I correctly fix the problem you might want to increase the intervalSeconds in the remoteConfiguration.json file in the WebUI's "Editor" page to 10 or 15. This setting determines how often the browser looks for a new image. The more often it looks the more likely it'll fail.

The obscured image was possibly due to me having brought the system indoors and placed on my bench and either having the camera intentionally obscured or the enclosure open and the cam was facing down

The changes you mentioned are me making a change, undoing a change, experimenting & 'learning on the fly' so to speak.

I ran the ls -ld /home/n8yel/allsky/config/modules, the result came back as drwxrwxr-x 2 n8yel www-data 4096 so that's good.

I'm not asking to you to solve everything 100%, just steer me in the right direction, which you've done (and Thanks) - I don't feel I'm doing too bad for a 60 some odd old geezer who's been out of the IT field (99% MS file & email servers, winders PC's & such in a corproate setting) for over 18 years.

Mar 22 '25 03:03 Flyfisherwiz

@Flyfisherwiz, I'm also a 60 some odd old geezer but have only been out of IT for about 3 years. Started my career at Bell Labs working on UNIX (which is what Linux is based on), so I'm very familiar with it.

Sounds like my power of deduction is still pretty good regarding why the images got dark.

I ran the ls -ld /home/n8yel/allsky/config/modules, the result came back as drwxrwxr-x 2 n8yel www-data 4096 so that's good.

Actually, I was hoping the permissions would be wrong, given a bunch of these messages from the web server:

PHP Warning:  copy(/home/n8yel/allsky/config/modules/postprocessing_periodic.json-last): Failed to open stream: Permission denied in /home/n8yel/allsky/html/includes/moduleutil.php on line 327

Please run ls -l /home/n8yel/allsky/config/modules. That might give me an idea why you're getting "Permission denied".

Let me know if the other things I suggest you do helped.

Created a service, today, to disable the Wifi power management on each re-boot of the Pi to keep the Wifi from going to sleep folowing the instuctions at this post to improve connectivity - I got to thinking about that this morning, if that could be an issue as I've had instances where I could not connect after a period of time/inactivity.

Mar 22 '25 14:03 Flyfisherwiz

Wi-Fi going to sleep definitely would cause issues. I would have thought that upoading a file every couple minutes would keep the WiFi on.
