Failed to connect to database: Error: Can't connect to MySQL server on 'locuscompare-us-west-2a.cvocub39nnri.us-west-2.rds.amazonaws.com' (111)

[7JVST]

Hi, I am trying to run this command locuscompare(in_fn1 = gwas_fn, in_fn2 = eqtl_fn, title1 = 'CAD GWAS', title2 = 'Coronary Artery eQTL')

but having the persistent issue for three days.

Error in .local(drv, ...) :
Failed to connect to database: Error: Can't connect to MySQL server on 'locuscompare-us-west-2a.cvocub39nnri.us-west-2.rds.amazonaws.com' (111)
Warning message:
In rm(config) : object 'config' not found

I have already tried my best but still do not know how to run it smoothly.

I am working on ubuntu behind a corporate proxy. So, I thought at first it was a proxy issue due to the lacking of MySQL server and AWS account on my device. But, when I use it on my mac, it is working like a charm without any installation and creation of MySQL server and AWS account. However, I still need to use this tool on my work PC because of input data privacy issue.

Does it mean I need to create an AWS account and adjust the network setting in it to access MySQL server on this URL 'locuscompare-us-west-2a.cvocub39nnri.us-west-2.rds.amazonaws.com'?

Please let me know how to run this tool behind a corporate proxy.
