I am trying to do the photometry with VPHOT as usual but though I was able to upload images I have been unable to get them displayed since yesterday.This is the error message I get:

Hi,

I just checked single image photometry on a couple of images without issues.

Can you share a couple of your images with NGIA so I can do a check?

These images have something peculiar?

Shared 2 images. They have nothing peculiar, much the same as the many other I have been able to measure with VPHOT so far.
Thank you

Hi,

It’s a transient issue related to the server load.

Yesterday initially I was getting the same message opening your images, around an hour later I was able to open and analyze the image.

Unfortunately in the last few days we had a surge in traffic with a lot of people managing large images and this stressed the server a bit.

Please retry at different hours if you see this error

I have retryed several times with no luck. VPHOT was able to load the image only once but still unable to load comp stars as I got a message saying “loading” for a very long time with no result. Perhaps the issue should be addressed somehow.
