why does images only upload on the second try on primal (npub12vk…pugg)?

Sometimes they refuse to upload, I have refresh a million times or change device to finally get my image to upload for sharing.

Is there something I need to know or change to avoid this in the future?

or shall I move to another provider?

any recommendations Nostratis?
