try to + base or try + -ing ....

Which  is  affirmation  is  more correctly?

I try to connect to  the  servers  but it's unreachable.  

I try connecting to  the  servers  but  it's unreachable.

Either sentence is okay.  I recommend studying how English changes depending on whether you are talking about one object or many objects.  That is a far more common problem for people learning English.

One object:

I try connecting to the server but it is unreachable.

I try connecting to the server but it's unreachable.

Many objects:

I try connecting to the servers but they are unreachable.

I try connecting to the servers but they're unreachable.

try to + base or try + -ing ....

Which is affirmation more correctly?

I try to connect to servers but it's unreachable

I try connecting to servers it's unreachable

thks

In English we would say something like: "I tried connecting, but the server was down."

Tried is the correct action verb for a past tense action. "I try" would be used for example: "every time I try to connect.." and trying would be used as: "I am trying to connect", or I was trying to connect."

Hope this helps.

try to + base or try + -ing ....

Which is affirmation more correctly correct?

I try to connect to servers but it's unreachable
(in this sentence, it is a repeated effort that you do every day. Is that what you want to say?)

I try connecting to servers it's unreachable

(this would not be correct.  To make this clear as a apst action, say either:

I tried to connect.  Or I tried connecting. The meaning is identical.

It means you tried a few times, in the past, with no success.

In your example, there is essentially no difference. There are cases, however, where the meaning changes a bit:

Try -- to attempt:

"He tried to get a job" -- but he couldn't find one.

"Try to get a job" -- I want you to attempt to get a job, you may or may not be successful.

Try -- to test something to see how you like it:

"He tried getting a job" -- he may in fact have gotten a job.

"Try getting a job" -- I believe you would be successful in obtaining employment, but you may or may not like having a job.
