I am in communication with a friend who is learning English.
I noticed her using "to" in the wrong context, but I'm unable to explain which rule she is breaking.
I can't access to Gmail.

"Access" can be either a transitive verb or a noun depending on context, and "to" can be either a preposition or a particle indicating an infinitive, and your friend is mixing up the uses.
"Access" as noun:
I need access.
I cannot get access.
"Access" as verb:
I cannot access Gmail.
"To" as preposition:
I need access to Gmail.
I cannot get access to Gmail.
"To" indicating an infinitive:
I need to access Gmail to send this report.
I need Gmail access to send this report.
I need to access Gmail for sending this report.
The reason that to is wrong in the original sentence is because the verb access is constructed with a direct object: I can't access the Internet right now.
When access is a noun, then you need to: Disabled people should have easy access to museums and galleries.
"to" is a preposition which can be used to indicate that a noun is the indirect object of a verb, rather than the direct object. For example, consider the sentence: "I am sending a letter to my friend". The verb is "sending". The direct object of this verb -- the thing being sent -- is "a letter". The indirect object, in this case, the thing receiving the letter, is "my friend".
In your example, "access" is a verb and Gmail is the direct object of "access". Therefore, no "to" is called for because there is no indirect object.
The example is, perhaps, confusing because someone could also say "I need access to Gmail", in which case the "to" would be correct. But note that in this sentence, the verb is "need" and "access" is a noun. "access" is the direct object of "need". The two examples can be misleading because in the first case, "access" is a verb, but in the second case, it is a noun. "to Gmail" in this case is a prepositional phrase functioning as an adjective modifying "access". This is a completely different function of the word "to" than its use indicating an indirect object.
Your friend associates it with "I can't connect to Gmail."
Access is akin to but different from connect to.
