I assume you are talking about local connection here, not from the internet, so it's ngiinx webserver you are talking about, not nginx-reverse-proxy? Can you at least ping the ip of the server? Syncing apps might not connect over http or https (or rather, they probably don't), which your browser does. Are you sure letsencrypt works properly and it's not just your browsers refusing to connect over https due to missing/miss-configured ssl certificates? Does forcing http connection at least give you some response? As for using wget to test: "wget --spider <url>" should get you some info. It should look something like this for correct setup using https: (enter url without http or https, I have redacted url and ip for obvious privacy reasons) $ wget --spider <your_url_here> Prepended http:// to '<redacted>' URL transformed to HTTPS due to an HSTS policy Spider mode enabled. Check if remote file exists. --2026-05-23 14:48:27-- https://<redacted> Loaded CA certificate '/etc/ssl/certs/ca-certificates.crt' Resolving <redacted> (<redacted>)... xxx.xxx.xxx.xxx Connecting to <redacted> (<redacted>)|xxx.xxx.xxx.xxx|:443... connected.

But as eselarm said above, we need way more information to be able to help.

Wifi chip?

I am running bookworm on my Odroid HC4, upgraded from buster. USB stopped working, which I believe to be U-Boot related. So I am looking for a newer version of the U-Boot package "linux-u-boot-odroidhc4-current", which is at 26.2.1. I tried to change the apt sources to trixie and apt updated, but apt doesn't offer me a newer package. I am not so keen on compiling it myself, so is there a way of finding/downloading/installing a newer package...?

I bought this board because it has 2 lanes. So I changed the number of lanes in the dtb from 1 to 2. I need confirmation of an expert but my quick speed test with 2 lanes looks promising : gt@yy3568:~$ sudo hdparm -tT --direct /dev/nvme0n1p1 /dev/nvme0n1p1: Timing O_DIRECT cached reads: 1062 MB in 2.00 seconds = 530.34 MB/sec Timing O_DIRECT disk reads: 928 MB in 3.00 seconds = 308.97 MB/sec gt@yy3568:~$ sudo dmesg | grep lane [ 4.183004] phy phy-fe8c0000.phy.6: lane number 0, val 1 [ 4.183679] phy phy-fe8c0000.phy.6: lane number 1, val 2 pcie@fe280000 { compatible = "rockchip,rk3568-pcie"; #address-cells = <0x03>; #size-cells = <0x02>; bus-range = <0x20 0x2f>; clocks = <0x0f 0x8f 0x0f 0x90 0x0f 0x91 0x0f 0x92 0x0f 0x93>; clock-names = "aclk_mst\0aclk_slv\0aclk_dbi\0pclk\0aux"; device_type = "pci"; interrupts = <0x00 0xa5 0x04 0x00 0xa4 0x04 0x00 0xa3 0x04 0x00 0xa2 0x04 0x00 0xa1 0x04>; interrupt-names = "sys\0pmc\0msg\0legacy\0err"; #interrupt-cells = <0x01>; interrupt-map-mask = <0x00 0x00 0x00 0x07>; interrupt-map = <0x00 0x00 0x00 0x01 0xcb 0x00 0x00 0x00 0x00 0x02 0xcb 0x01 0x00 0x00 0x00 0x03 0xcb 0x02 0x00 0x00 0x00 0x04 0xcb 0x03>; linux,pci-domain = <0x02>; num-ib-windows = <0x06>; num-ob-windows = <0x02>; max-link-speed = <0x03>; msi-map = <0x2000 0x66 0x2000 0x1000>; num-lanes = <0x02>; phys = <0xca>; phy-names = "pcie-phy"; power-domains = <0x11 0x0f>; reg = <0x03 0xc0800000 0x00 0x400000 0x00 0xfe280000 0x00 0x10000 0x00 0xf0000000 0x00 0x100000>; ranges = <0x1000000 0x00 0xf0100000 0x00 0xf0100000 0x00 0x100000 0x2000000 0x00 0xf0200000 0x00 0xf0200000 0x00 0x1e00000 0x3000000 0x03 0x80000000 0x03 0x80000000 0x00 0x40000000>; reg-names = "dbi\0apb\0config"; resets = <0x0f 0xc1>; reset-names = "pipe"; status = "okay"; pinctrl-names = "default"; pinctrl-0 = <0xcc>; reset-gpios = <0x58 0x1e 0x00>; vpcie3v3-supply = <0xcd>; phandle = <0x271>; legacy-interrupt-controller { interrupt-controller; #address-cells = <0x00>; #interrupt-cells = <0x01>; interrupt-parent = <0x01>; interrupts = <0x00 0xa2 0x01>; phandle = <0xcb>; }; };

After much trouble with my old build environment I cloned Hqnicolas build repo. Now I can confirm that it seems to work. I made a quick speed comparison between the ssd and my external USB drive: gt@yy3568:~$ sudo hdparm -tT --direct /dev/sda /dev/sda: Timing O_DIRECT cached reads: 178 MB in 2.00 seconds = 88.89 MB/sec Timing O_DIRECT disk reads: 322 MB in 3.01 seconds = 106.88 MB/sec gt@yy3568:~$ sudo hdparm -tT --direct /dev/nvme0n1p1 /dev/nvme0n1p1: Timing O_DIRECT cached reads: 1160 MB in 2.00 seconds = 579.44 MB/sec Timing O_DIRECT disk reads: 690 MB in 3.00 seconds = 229.89 MB/sec Thank you very much to both @Arthur Gu and @Hqnicolas
