Hi, i have some problem to start pydio cells. After the installation and “./cells start” i have this output **panic: runtime error: invalid memory address or nil pointer dereference** \*\* [signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0xf8928a]\*\* * * * \*\* goroutine 65 [running]:\*\* some hints?

Hi, it could be that you are lacking RAM and therefore the binary does that, could you give me your system specs, the os and also the php, mysql versions. ---

everything seems to meet the requirements so it’s not the issue, maybe you could try to do a clean re installation if it’s was a recent one, remove the the pydio folder located in `~/.config/`, download the latest binary ( if it wasn’t already done, latest version is [1.0.0](https://download.pydio.com/pub/cells/release/1.0.0/linux-amd64/) clear the database that was created it was named `cells` by default. edit : if you have data that you want to keep don’t forget to back the `data`. ---

I did some additional testing on this issue today. I only receive this error when attempting an installation using an outside world ip address . If I create a server using private ip address the installation works. I would like to know of those who have posted in this thread are using outside world ip addresses to help narrow this issue down. ---

Interesting… I’ve received the same error on an 18.4 installation and using an external IP. So you’re saying it works if you install an internal IP… but then I guess access would only be available when in the local network? I have this installed on a dedi box, and external access is a must have for me. I wonder if there’s any way to get it installed and accessible externally. ---

I did additional testing yesterday and here are my findings. My setup is a VMWare ESXi host that can be accessed internally and externally. My first attempts were to install in a VM that was for external use only. The installation completes successfully but fails on startup with the error listed in this thread. I’ve tried binding to local host/outside ip and outside ip/outside ip and this error occurs everytime. If I install the VM for private use only the server start is successful every time with all features I’ve tested working. My gut feeling tells me it’s a GO Lang / NATS http redirect issue. I did the install one more time but when I configured the VM I installed it using two network adapters. I put one adapter private and one adapter public. When I did the bindings I used localhost:8080/Outside IP:8080 and the server successfully started but it is very slow. I also noticed that it’s not able to write any data to any folder as a user or as an admin. So in short, my best guess is some type of http redirect issue but I’ll leave that up to the developers to determine now that updated the post with this info. ---

Working solution for me using an outside IP address in a virtual machine requires 2 network adapters. I can not make it work using only one. In the creation of my virtual machine I set one adapter for my internal network of 192.168.x.x and a set the other adapter for my real world network of 65.x.x.x . During the installation phase I set the internal listening IP address to my outside IP of 65.x.x.x:8080 and I also set the external listening port to my external IP of 65.x.x.x:8080 . I can connect using a web browser to url [http://65.x.x.x](http://65.x.x.x).:8080 . Everything works now including writing data to folders which was failing before. If I log in as an admin and look at the Services it shows ALL services bound to the internal network of 192.168.x.x . If I try to connect to url [http://192.168.x.x:8080](http://192.168.x.x:8080) from the local network I get the error 404 Site 192.168.x.x:8080 is not served on this interface. I hope this helps others solve running Cells on a real world IP in a virtual machine. I’m very confident that trying to use an outside IP address using a single network adapter results in the panic:runtime errors due to some type of http redirect / NAT issue. ---

I was using a single and public IP address as well. Added a second adapter with a local IP (192.168) and now it runs! cells seems to bind to 127.0.0.1 and 0.0.0.0. Odd that it really needs some local IP. I hope that can be fixed. ---

Hi, the issue is with the external bind, you can keep your internal bind as it is (0.0.0.0:8888) > [@jpeizer](#): > > External Host (used to access this machine from outside world if it differs from Bind Host): 0.0.0.0:8888 Use the server’s public IP + the same port as the internal bind (in your case 0.0.0.0:`8888`) or a Domain name if you have one and you should have access to it, also. > [@jpeizer](#): > > WARNING: File descriptor limit 1024 is too low for running Pydio Cells Home Edition in production. At least 8192 is recommended. Fix with “ulimit -n 8192”. panic: runtime error: invalid memory address or nil pointer dereference Change this with: `ulimit -n 8192` [Next page](https://forum.pydio.com/t/panic-on-pydio-cells-start/1182.md?page=2)
