Can not connect to server

Seafile Client
1

1. ENV

Server: seafile-server-7.0.5 @ ubuntu 16.04
Client: Seafile Client 7.0.4 @ windows 10

2. Problems:

2.1 Waht I can NOT do

Can not connect to server

it says Can not connect to server while checking server info

can not sync library

When I click “sync this library” over my library, it says:“Failed to add download task: Task is already in progress”. But I CAN NOT find anything under the target dirctory

2.2 What I CAN do

I CAN list,download,rename,upload files and directory in my library

My question

Why my client always syas “can not connect to server” and can not sync my library?
If it really can not connect to my server, it can’t list,download,rename,upload files and directories as well, I think.

Welcome to the Seafile Community forum!

You would assist us in helping you if you posted your conf files (ccnet.conf, seahub_settings.py, …) I am pretty sure that there is a small config problem that can be easily solved.

Thanks for your reply, here is my configurations(I didn’t apply much customized configuration, except for the server port ):

Hi. i get the same issue also. Anyone able to help? have installed seafile using docker container

5

Hi @jonneymendoza and @wuyudian1,
could you please ensure that both seafile AND seahub are properly running?

Just check the output of

ps aux | grep seafile

on your server.
Thanks!

6

my output says this:

ps aux | grep seafile

i used this to run seafile:

docker run -d --name seafile -e SEAFILE_SERVER_HOSTNAME=192.168.1.111 -e SEAFILE_ADMIN_EMAIL=me@gmail.com -e SEAFILE_ADMIN_PASSWORD=myPassword -v /opt/seafile-data:/home/media/wd4tb -p 80:80 seafileltd/seafile:latest

7

@jonneymendoza
When running it with the command you mentioned, you should be able to point your browser towards 192.168.1.111 and seafile should appear.

Otherwise please check the logs:

docker logs seafile

Also: Is the PC you are accessing Seafile from in the same LAN as your Server?

8

yes i can login though the web broswer fine but the actual seafile client on my laptop says cannon connect to server . The client in question is my laptop running linux pop OS. same issue when i try it on a windows 10 machine.

9 
docker run -d --name seafile \
   -e SEAFILE_SERVER_HOSTNAME=192.168.1.111 \
   -e SEAFILE_ADMIN_EMAIL=me@gmail.com \
   -e SEAFILE_ADMIN_PASSWORD=myPassword \
   -v /opt/seafile-data:/home/media/wd4tb \
   -p 80:80 \
   seafileltd/seafile:latest

Mind the order in which the volume (-v) needs to be specified: The entry: /opt/seafile belongs to a path on your host, the entry /home/media/wd4tb belongs to a path inside docker. I think it has to be the other way round, if you want to use /home/media/wd4tb as path on your host, try it like this:

    ... 
    -v /home/media/wd4tb:/opt/seafile \
    ...

The documentation on github is totally f** up at this point.

10

Also, if you can’t connect with the seafile client, please post the output of

docker logs seafile
11

Yes the docs for this software is not good. THe /home/media/wd4tb is a ext attached hdd that i want all my seafiles to be in including configurations so its easy to move it around and backup/restore etc

edit: New logs after i switched the -v directory locations as you mentioned

OK when i swithed the -v storage location around and restarted the seafile container i get this error now from the docker logs

Ok I realised /opt/seafile/ is not possible to use as container path for the volume, rather there is another directory, /shared. Please try it again with

    ... 
    -v /home/media/wd4tb:/shared
    ...

Now docker should start again, normally.
You can then access a bunch of files inside /home/media/wd4tb on your hdd.

Next, you can have a look at your Seafile Client logs in PopOS Linux under ~/.ccnet/logs. Look through seafile.log for any messages of failed connections etc.

15

After doing that, am unable to access my seafile at all from the web browser. the logs state that it has succesfully created the seafile admin etc but i cannot launch it from my browser

Okay, we are getting to the problem. The problem is with the nginx configuration. Something is configured wrong there, so you will have to go inside the docker container and execute some steps there.

First enter the docker container (it must be running already) with

docker exec -it seafile bash

then please paste the output of

cat /etc/nginx/sites-enabled/seafile.nginx.conf

also, ensure that the nginx logs are present:

ls -la /var/log/nginx/

Please post the output of both commands (the last two).

Hi.

here is the output from that command

cat /etc/nginx/sites-enabled/seafile.nginx.conf

Ok, the file looks ok, the logs dir also. Now please check (again inside the container)

tail /var/log/nginx/error.log

and

tail /var/log/nginx/access.log
