I have attached the screenshot link in the second you sent your response, so you can check it out if you didn't notice.
Is that the error you asked for? It says something about overly sized packet.
I guess I can increase the size of packets that the client & server accept, but I'm not sure if this error isn't an underlying issue of something else, since this shouldn't happen in normal circumstances, right?
EDIT(1): So I increased the size of acceptable packets and managed to upload it successfully. I also eliminated like 99% of the connection refuse errors, however, there is still 1 or 2 going around. Currently checking any other potential issues.
EDIT(2): So, the issue with missing table seems to be fixed, however, the auth still can't connect.
AUTH SYSSER:
SYSERR: Dec 15 17:08:15 :: socket_connect: HOST 127.0.0.1:15000, could not connect.
DB SYSSER:
SYSERR: Dec 15 17:08:13 :: Start: TABLE_POSTFIX not configured use default
SYSERR: Dec 15 17:08:55 :: Process: FDWATCH: peer null in event: ident 23 (found on the forum that this is not exactly the error)
EDIT(3): So, I tried to check the my.cnf file to see if there is everything alright in the Mysql settings, but I can't seem to even locate it in my files? That might be the reason why it can't connect to 127.0.0.1 I guess? The thing is, Mysql seems to run fine, so it's pretty confusing.
