Hi all,

F4-424 V6.0.783

Encountering two issues with the mobile app(v.3.4.033):

1. In "Photos" it does not show any thumbnails/preview of the photos I have, just grey squares. Tried to regenerate thumbnails but no changes.

2. When I go into file manager to download a file (photo or doc), it creates a download task but will stuck on waiting forever.

Wondering if there are any insights to support the above please?

Thank you for your feedback!
We discovered this issue a few days ago and have been investigating it. We've determined that some certificates in the system have expired, causing TNAS mobile to experience download or load failures when used on a local area network. Our team is currently renewing the expired certificates; please be patient.

Temporary solution: Try accessing your NAS remotely using the TNAS mobile app.

Hello,
I just bought a F2-425 (TOS V6.0.794-01324, TNAS mobile V3.4.042) and I'm experiencing the same issue.
Your latest comment is from october 2025. Has this issue yet been resolved or are you still looking for a solution?
FYI: it works remotely, but it is terribly slow.

Hello,

The issue has now been resolved. The problem you encountered was likely caused by a slow network connection. We recommend checking your current network status—for instance, by trying to access other websites or services to see if they are experiencing similar latency or slow loading speeds.
