Hi everyone, After updating to the latest version, Iā€™ve noticed the following: No matter what kind of document I upload, it always shows as ā€œ0 bytesā€ in size. Is there a solution for this? Iā€™m using the Opera browser, which worked fine before. However, Iā€™ve noticed that it works in Chrome, so my question is: how can I fix this so it works in Opera again? It doesnā€™t seem to be a general Nextcloud problem. But it would still be great if someone could explain why it works in one browser and not another. Iā€™m not getting any error messages. My OS is: CachyOS latest build with kernel 7.x I installed Opera via ā€œFlatpakā€. Thanks for the support. Apart from this problem, I havenā€™t noticed anything else wrong with the browser. **[Nextcloud Hub 26](https://nextcloud.com/)Spring (34.0.0):** - Operating system and version _(Truenas Linux version :_ 6.12.33-production+truenas #1 SMP PREEMPT\_DYNAMIC Mon Feb 23 17:38:27 UTC 2026 x86\_64 GNU/Linux\*)\* - postgres version 18.3-trixie - nginx version 1.29.6: - Reverse proxy npmplus (version 2.14.0): [GitHub - ZoeyVid/NPMplus: a fork of nginx-proxy-manager Ā· GitHub](https://github.com/ZoeyVid/NPMplus) - PHP version _(8.4.18_): - Is this the first time youā€™ve seen this error?

Hello, I thought it was clear what I meant. Iā€™ll upload a ā€œFileā€ so you can see. ![image](https://help.nextcloud.com/uploads/default/original/3X/e/1/e19ca99635570036b145e4c610ed0de7f0e1ad67.png) All Files from Opera has 0 Bytes from Chrome work. But the question is why it works in Chrome and not in Opera; I havenā€™t changed any settings. Best regards ---

just a random thought: Is Opera VPN disabled? ---

correct , VPN is not activated. Otherwise, I have no problems except for the internal Nextcloud instance, but the problem only affects the Opera browser; it seems to work with Chrome. Maybe I should wait until the next update; itā€™s well known that new updates always bring new bugs. Iā€™ve already gone through a few Nextcloud updates and always had new problems on the instance after an update. Sometimes the notes suddenly stop working, other times itā€™s the browser issue. Well, itā€™s never boring, that much is certain. ---

So, with version 34.0.1 the problem was fixed, but it also introduced new problems, including some that I experienced after the update. I think Iā€™ll mark it in my calendar for when a Nextcloud update comes out that doesnā€™t have these issues for me. But I think thatā€™ll be a long wait. ---
