Instapy: selenium.common.exceptions.WebDriverException: Message: chrome not reachable

[FBosler]

New bug, stopped my script twice now. I am running it on an ubuntu server. Script crashed after roughly 400 (for the first time) and 450 (for the second time) likes. Please find below the traceback. Cheers

[timgrossmann]

@FBosler Could you give some stats about how and where you're running it?

[FBosler]

Sure. It just crashed for the third time in a row, this time at the first tag.

excludePpl = ['list of my friends']

InstaPy(username='myName', password='myPass!', nogui=True)\
  .login()\
  .set_dont_include(excludePpl)\
  .set_upper_follower_count(limit = 500)\
  .set_do_follow(enabled=True, percentage=10, times=1)\
  .set_do_comment(True, percentage=15)\
  .set_comments(['Fantastic!', 'Awesome!', 'Brilliant!', 'Cool!', 'I love it', u'⭐']) \
  .set_use_clarifai(enabled=True, secret='mySecret', proj_id='myProjectId')\
  .clarifai_check_img_for(['nsfw'])\
  .like_by_tags(['myTags'], amount=300, media='Photo')\
  .unfollow_users(amount=75)\
  .end()

I run it by calling (manually, i.e. no cronjob):
my script with: nohup python3.5 LikeScript.py &

I run it on:
DigitalOcean Droplet with: 1 GB Memory / 30 GB Disk / Ubuntu 16.04.2 x64

[timgrossmann]

@FBosler Do a ps aux on your server... There are probably some zombie chromes running there...

Simply turn it off and on on DO or do a reboot

[FBosler]

Good idea. However, I already did that. There were no zombies :) which is good I guess, cuz zombies are bad.

Can try the reboot later. Have you encountered the problem before?

[timgrossmann]

@FBosler Yes, I find it really interesting, that, given you set it up with the "How_to", people encounter so many problems when my script runs without any incidents for 3 months now 🤔

For me it was simply reboot

[FBosler]

Error persists, even after reboot. Really no idea whats going on ... :(

[timgrossmann]

@FBosler Ahh, this could also be due to the wrong version of the chrome driver you put into /assets.

Try to both update Chrome on that machine and remove the chrome driver and download it again

[FBosler]

I did follow the "how to" step by step though. I mean, you really made it foolproof with the script and all.

How would I go about updating chrome on ubuntu?

Tonight everything worked as expected. I didn't update anything though. Very strange.

[timgrossmann]

@FBosler Well, if the installation worked, you could just do apt-get update and apt-get upgrade

This should upgrade all dependencies including the chrome browser.
Also make sure to get the latest chrome driver.

If that does not work, please try with a new droplet and follow the instructions one by one.

[timgrossmann]

@velocityzen This can be due to zombie instances of chrome still running in the background...

You can e.g. add a reboot to the end of your script to make sure that you always have a clean droplet for running the script

[velocityzen]

@timgrossmann Thank you! After reboot it goes smooth. I'll try to add killall -9 chrome after the "show".

[FBosler]

I don't think we should close this. For me the error popped up again last night. I don't know the reason yet, but it's not always solved with a reboot.

[IPYWorld]

I had this error from a couple days ago. Doing apt-get update and apt-get upgrade, and then git pull to update InstaPy fixed everything for me.

I am also running on Digital Ocean and used the How to steps.

[FBosler]

@IPYWorld : same here, I went through the same steps and It did work fine two or three times until last night when the same bug occured again. As I said, I would leave this issue open for information gathering.

[FBosler]

Bug still happening ... weird:

[FBosler]

@timgrossmann sorry to bother you with this, but since I am fairly new to servers I figured it wouldn't hurt to ask. What do I have to add to my python script to reboot the server? Can I just add a simple reboot at the end of the script?

[timgrossmann]

@FBosler

from subprocess import call
call(["reboot"])

should do it.

[MelomanCool]

I've had this issue with Selenium itself. The problem was that I didn't have enough memory on the server, so Chrome just crashed.
