Hm… sure enough looks like it didn’t get booted. Then we’re going to need more output for Rocket.Chat startup logs.

__updated to insert the entire log.
It looks like something is trying to use the file system at a path that doesn’t exist and it can’t create at since read only.
Can you do: rocketchat-server.mongo
Then execute:
db.rocketchat_settings.find().forEach(function(s) {
if (!s._id.match(/^Assets/) && !s._id.match(/^Layout/) && s._id !== 'css' && s.value !== s.packageValue) {
print(s._id + ' - ' + s.value);
}
});
It will spit out any setting changed. So will need to censor out any secrets or domains. The file paths and file related settings we are most interested in.
I’ve inserted that in the rocketchat-server.mongo terminal and it returned nothing.
That piece of code is immediately followed by “rs0: PRIMARY>”
You might need to type use parties first to select the database (this is default db name in snaps)
Should I post the custom .css output here as well? There’s a lot.
Nah that shouldn’t have any effect on boot up. Can leave that out

Alright this is what I suspected.
We’ll need to drop into a mongo shell again. Also switch to parties db just like above. Then choose which path forward
If you want custom emoji on file system you can update this value:
db.rocketchat_settings.update({_id:”EmojiUpload_FileSystemPath”},{$set:{value:”/var/snap/rocketchat-server/common/emoji”}})
Or replace with folder that is snap writable. See more details here: Deploy with Snaps - Rocket.Chat Docs
Alternatively switch it to use gridfs
db.rocketchat_settings.update({_id:”EmojiUpload_Storage_Type”},{$set:{value:”GridFS”}})
Once you do one or the other you should be able to restart Rocket.chat.
Looks like this value was changed while it was running and must have never needed to restart since set. Then the update caused it to and failed to start up because it had web address instead of file system address and it couldn’t find the folder
I get this:
db.rocketchat_settings.update({_id:" EmojiUpload_Storage_Type"},{$set:{value:"GridFS"}})
WriteResult({ "nMatched" : 0, "nUpserted" : 0, "nModified" : 0 })
After exit, I restart rocketchat and mongo, but still can’t access my rocketchat instance.
I’ve tried running the following code again:
db.rocketchat_settings.find().forEach(function(s) {
if (!s._id.match(/^Assets/) && !s._id.match(/^Layout/) && s._id !== 'css' && s.value !== s.packageValue) {
print(s._id + ' - ' + s.value);
}
});
And still get EmojiUpload_FileSystemPath - https://domain.com/emotes
I’m not an avid mongo user, I thought maybe I exited without saving but I can’t find a command that saves the changes to a database so I assume it saves the changes automatically.
What could be a problem?
Oh ouch looks like i typed on my mobile a space before the setting name. Shouldn’t be any space between the quote and setting name. Fixed previous post in case any others copy
db.rocketchat_settings.update({_id:"EmojiUpload_Storage_Type"},{$set:{value:"GridFS"}})
Great, everything works now.
I must note that was some stellar support of an open-source user with among the fastest turnarounds I’ve ever seen.
Thank you for your time and attention, Aaron.
Happened to be able to help and see it through. Definitely not always this quick 
Glad you got it though!
