Internal Network Domain Problem (Apache2, Pi-hole)
Hey, I am hosting a website and Pi-hole on my Raspberry Pi. The website is accessible to anyone on the internet and operates correctly; however, for some reason, I cannot access it locally. Within the LAN, it seems to work intermittently, and I cannot access it at all over Wi-Fi. The browser displays a 'connection timed out' error. The Raspberry Pi is correctly registered as a DHCP server in the router. Unfortunately, I have tried various solutions and still do not know what the issue could be.

Wi-Fi communication
I want to establish communication via WiFi with a laptop. I want the Raspberry Pi to send an image to the laptop, where it will be processed using the OpenCV library. Then, the laptop will send appropriate commands back, and the Raspberry Pi will transmit them via UART. I am a beginner and don’t know how to do this. Do you have any ideas?

Specific Boot Failure from SSD on Raspberry Pi 5 with Radxa Penta SATA Hat – SDRAM Error
Hey everyone,
I've been troubleshooting an issue with my Raspberry Pi 5 (8GB) using a Radxa Penta SATA Hat and four SSDs (one for boot, the rest for NAS storage). I'm trying to boot from the SSD, but I'm getting 8 flashes on the RPi, indicating an SDRAM error (firmware issue or SDRAM damage).
I've set the boot order correctly using a micro SD card, and everything works fine that way. However, when I remove the micro SD card and try to boot from the SSD (with Raspberry Pi OS Lite already configured and SSH enabled), I hit this error.
Any ideas on how to resolve this? Thanks in advance for your help

Apache2 server won't expose to internet
Hey there, so I've been trying to setup a simple webpage using apache2. I've been able to set it up so I can connect to it through local ip, but if I search for my public ip I don't get the webpage.
I've already setup the needed port forwarding of port 80 to the static ip of the raspberry pi and configured the ufw of to allow 80/tcp Anywhere.
I'm kinda lost here, I've previously setup my raspberry pi (same static ip) to have a public webpage, that worked but I wanted to restart and now it doesn't work (so I would think it's not a problem with port forwarding)
Do you guys have any idea of what to try?

Raspberry pi pico personal diary or sorts
I was thinking, and this is something i thought about for a while, but i dont know if its even possible. its like a digital diary/notepad that you can write thoughts in without the need of a pen or paper. i have the idea and its pretty simple. its just a pocketable device, almost the size of a blackberry or even smaller. i want it to have a keyboard, but it can even be t9 to keep the small factor, a good enough screen and good battery life. but i dont know if its possible due to the pico being an mcu and what the ui will look like and how i will get it to be built. i have my own screen, raspberry pi, but im missing the keyboard and a battery that will be suitable.

External psu for servos requiring thicker cables?
Hey i have 4x 20kg servos (each 4.8-6.8V) connected through 4 signal cables to the pi and then the + and - connected to an external power supply (5V 8A). Only 2 servos work, but its not the fault of the servos because i tried swapping them and they still work. Someone told me jumper cables maybe cant handle the 8A and so i should use thicker cables for that. Is that true?

Batocera on NVME / Not loading any games
I have the following problem:
I flashed a Batocera image onto an NVME SATA drive using a USB enclosure. When I connect the drive with the USB enclosure to the Raspberry Pi 5, everything works fine.
However, when I remove the NVME and install it directly into the Raspberry, the Raspberry boots into Batocera just fine, but when I start a game, the screen goes black and nothing happens. The same thing happens when I press F1 to access the file manager. When the NVME is connected via USB, everything works, but when I install it directly into the case (ARGON 40 NEO 5 NVME PCIE Case), it boots, but I can't start any games.
The artwork is visible. At first, I thought that maybe it can't mount the second partition with the ROMs, but then the artwork wouldn’t be visible either, right? Unfortunately, I'm a total Linux newbie, so I have no idea. But what could be the cause of this?

Fallback WiFi on boot, possible?
Hi there, I have two connections set up through nmcli. When I boot up the pi, I would like it it to attempt to connect to a specific one of those connections and if it fails to try the other connection. Is this possible? How would I do it? I am familiar writing in Python if that's needed, but I'm not super familiar with Linux. (I want to set this up via terminal, I am running the pi headless and configuring it over ethernet currently)
The idea is if I boot the Pi and my phone hotspot is up then it will connect to that, otherwise it will attempt to connect to my home WiFi.

raspberry pi 4 can't be found on network
hello, i'm trying to do a headless setup on my raspberry pi 4 but i can't find my pi on my network.
i'm using a 256gb microSD card and made sure to format it to FAT32. i flashed the raspberry pi os 64-bit and also tried the lite version. i set up the wireless LAN and allowed SSH before flashing.
when i try ping raspberrypi.local in my terminal i get ping: cannot resolve raspberrypi.local: Unknown host. i made sure my computer is connected on the same network. when i scan the network, i don't see my raspberry pi either.
does anyone have suggestions on how i can troubleshoot this?

Password Error
Hi! I am currently trying to set up my raspberry pi 5 128gb storage 8gb ram on my lenovo laptop, and I have ran into some errors. I tried searching online and nothing has helped me. Whenever I want to connect to the pi, the following occurs
pi@[my-pi-ip]'s password:
Permission denied, please try again.
pi@[my-pi-ip]''s password:
Permission denied, please try again.
pi@[my-pi-ip]''s password:
pi@[my-pi-ip]': Permission denied (publickey,password).
I tried changing the password via Raspberry Pi Imager and rebooting the pi, but whenever I change the password, it automatically resets back to a random 25-letter long obfuscated text.
I attached two images one containing my password (the shorter one) and the other containing the weird text that disappears when I try to select it. What do i do?

Best way to connect two remote Pi's
Hey, hope your doing well. So I will describe the situation I have and explain my problem. There is an Pi5 (has wifi and net power) that acts as an server somewhere deep in a building. And then outside there is a zero 2W that is connected to an camera( has no wifi and powered by batery) . How would I stream the video from the zero 2w to my server. There like 200 meters apart separated through doors and walls. I have thought of the following solutions.
- Wfif bridge
- High-Gain WiFi Antennas( If possible??)
- Radio waves

And after some searching I came acros these two components. I do not have a lot of experience with this so whill these do the job or does anyone else recommend other recievers/transmitters for streaming video. preferably from the same vendor.
