I have tried changing network connections to no avail (although this is on my normal network that usually works fine). It won’t sync to AnkiHub; it tries syncing, for about a minute, then gives this response:
Here is the “upload logs” file name: ankihub_addon_logs_f02cf_1731984663.log
Hello,

Please let me know if that answers your question, and if there’s anything else I can help with.
